Nice addition, but a few cautionary notes: (in case no one else pointed these out already)
Biggest #1 -- do not rename and edit the stock Illusion girls. When the next expansion/DLC or BR is released, the included files will overwrite them each time. You can open an existing girl then choose "Save New" and it'll rename her card ID based on the new qualities and time stamping, making her unique. You don't want to have girls sharing card numbers with the included cards or the BR girls either. Any editing or playtime, save new, otherwise you'll lose your progress later. You can always adjust the sliders where you want them with Agent Trainer.
Secondly, if you want to progress the girls for access to the Housing Island later on etc. You may want to add one heart at a time then speak to her, or adjust her stats (I think like +3500 total parameter[flavor] exp or so is the 4th heart) while you have her following, then speak to her 4 times in a row, to progress the storyline flags properly and unlock the island naturally. This would more or less only apply to the new game scenario, not using the 100% or Quick Start options.
(5-8) If you activated the ExtraGirls mod, and are on the beach, face the mountains, take the left path, there is an active Terminal 3/4 of the way to Shan's House that is only 250-300ft from your starting location (maybe a 20-25 second run). That is just simpler in my opinion.
(10) In regard to "Max out flavors/parameters" that really depends on what kind of attitude towards sex you want her to have and how resistant to H you want her. If Humanity/Reason, Vigilance/Wariness, and/or Darkness is high she will become more resistant and conscious to many things like fetish/BDSM stuff, peeping, area positions (bath/toilet/hole etc., and may even scream and run away covering herself to the nearest closet where she will load her default outfit) and sex toys.
(11) Adding all H skills may not be the most desirable thing as well since some of this sort of conflict with one another. Also the "sensitive" parts will shift your animations quickly if you do not freeze/lock the gauges. If she has "weak pussy/crotch" and "Masterpussy" at the same time, your positions will climax for both doing vaginal insertion positions in a few seconds, resulting in the final animation pre-climax playing 2-3 times faster. This may not be desirable for all people. Also H-Skills like "Sexual Aversion" (decrease in sexual desire), "Homosexual," "Lesbian Lover," "Self-Satisfied," and "Dissatified," are all against what you seem to want to achieve, which is a Male hero banging a female NPC. The rest all add specific desires, for instance, if you give her "Lust Devil," "Heat," "Wants to be Broken," "M," and "Anal Passion," you will have a girl that wants to be forced in the butt until she is weak, but if you have "Nympho," "Techni Shan," "Cumshot Lover," "Loves to Service," and "S," you will have a girl that wants to jump you and force you into an oral service H and end the scenario with a bukkake. This will add bonus stats for the H into different categories of her growth as well. Unless you are cycling through all the positions (and even then) she will come away disappointed in one way or another, unless you literally insert in all holes, cum in and out of all holes, bang her until weakness, force her to masturbate, then give her an energy drink to perk her back up from sex. With all you still cannot satisfy her alternate cravings and if you engage in 3-way sex to include another girl, you cannot do the former.
(12) Trust/Reliability has to be over 500 for her to have a high rate of probability that she will follow on the first request.
(15a) You can switch locations in H with the icon that has the 'grid and plumbob' on it... No need to exit to change positions. Also with the "BetterHScenes 2.0.0" mod in place, you can set the "H Point Search Range" to 1000m and use the camera to find distant locations with H points and move up to 1/3 the island away without exiting the H scene. From the Ruins Base to the Beach Base is 2-3 moves, which are more or less instant teleportation.
(15b) You can lock her stats/parameters/traits/needs-desires by clicking the name of the option to turn it red in Agent Trainer, so you do not need to refill anything.
(15c) With MadSkills activated you can also give them the "Super Sense" skill which will make them fast travel nearer to you and then path to you. Although this is also prone to errors sometimes. e.g. You have 8 girls on the island and only 7 make it. The more girls the higher the likelihood of more frequent glitches.
Making New Save
(2) Instead of New Game I would suggest Quick Start if you are just trying to get to H quickly without using the records of the other save from the 100% save file.
