Question about exclusive version of Tower (Patreon)

All you know that I write earlier about exclusive version of Tower, here was original version, extended version which have customization for characters, and I wanted to create exclusive version too, where should be additional poses to each monstergirls in tower, but I meet some problems with that during creation extended version - for some reason game starts have heavily lags with additional sprites in it, so if I add exclusive version directly to the Tower game file it will decrease FPS even more, so, I now think about create a separate special exclusive gallery that will go along with the extended version of the game, it will be an additional separate file and you will need to open it separately, like some adultgames make main game file with all things and additional file with gallery
Anyway Flash can't support this huge type of projects (even for work with that I need 8gb of RAM, and for compile this I need 20gb of RAM ^^" )
So I can't be sure that it will work correctly if I try add it in main game file, so, what do you think about that? Should I try to add this in game or not spend time on that and just make separate gallery file for you? ^^
