To be honest I could care less. Just as long as it's extremely clear to folks:
If you pour ketchup in your glass of milk, then don't bitch if it tastes like shit... that's on you. So, if your game gets fubar'd due to mixing mods, don't cry about it later, please.
But just know that the entire gallery is included in SanchoGallery independently unlocked by default. PeepingTom & Donuts I only give hints at while in-game so you can work as "achievements". So, to summarize
the only advantage to the above are PeepingTom & Donut unlocks if the player decides to do so. Drink your milk.
