It makes sense, and I have a great idea on how to keep the game fresh this way. There are certain characteristics which make characters unique, and as the game adds . However...this can go deeper than mere cosmetic and fighting changes. My idea is that, let's take the Amorous characters for example. I personally think that crossing the boundary between games would be amazing fun (especially since the dating sim is so well-liked). If we looked at Seth, he would be agile, but very weak. That might be enough for NORMAL fighters, but what if the enemies interacted with his weakened form differently. The boys that would normally be riding Vergence would instead be raping Seth, lifting one of his legs and fucking his ass as he claws at the ground. trying to get to the other side of the screen (even if he remains static it's a good visual). This kind of diversity depending on characters would make it easy on the coders (since each response per enemy would be tied to that character) and very appealing for us players who might not want to watch our raptor friend being ridden all day. This is merely the ramblings of a horny player who desperately needs a game like BBS to stand tall. Please comment below about this topic, as well as other characters you may want to see (as well as how the enemies would interact with them).
