You could go with that and I can see the charm in it. Storywise Grace is the only "milf" that is actually a few years older than the MC and there is history, chemistry and dynamic in it's own in the dialogue between MC and Grace. Plus her kid is fun. Calling the MC "old man" with them sly eyes and witty dialogue, I had a blast seeing all that. It is one of the exceptions as you mentioned above that I can tolerate without any prejudice. But taking into consideration that MC went undercover against a criminal Syndicate called the "Syndicate" like in the "Almost Human" TV series with Karl Urban, I made the (moral) choice of not involving the MC with a woman that has a little kid in order not to make them potential targets for my enemies. Considering that all close to the MC are potential targets, I went after the Florentino sisters. Both gorgeous and to my liking proportion wise, but also considerably well protected, plus the Florentinos (Tess and Gabriel) are in the loop, cause their family is part of the mob front (so called city elite) that has undergone considerable public "transformation" from dirty to washed money probably and "legal business"... Plus they are actually funding the MC on the side constantly each month. It makes sense aligning with them story wise and it comes natural... it has a lot of background also. MC and the elder brother Rick, MC mother Noir and Tess, MC father Liam and Gabriel are also old buddies. So I went with them...
