Kind of hope JSK does a mecha musume game sooner or later, just as a change up from the modern and fantasy settings we've gotten so far. I know we kind of got something with Fuuma Girl Maisa, but that was more a Taimanin style body suit than mecha musume.
I also wouldn't mind another multi girl game like we got with Sempai, Kouhai, and a Gifted Ojisan, but more in the line of you can pick from three or more different girls to fight, each with their own ending paths, and once you beat them all, you unlock Extra Mode where you fight them one at a time for a shot at a harem ending. Something that could be challenging to do, unless it recycles a lot of animations. But would be interesting if he could pull it off.
Another idea would be a disarm mechanic. Like, say, if you target her arm, if you break the armor on the arm, she drops the weapon she has in that arm, and needs to pick it back up before using the attack tied to it again, but the clothing would still be torn off. Would make striping the girl's clothes off more interesting if, as doing so, she temporarily or permanently lost attacks, making her easier to predict without the mind reading ability that usually is the last thing you unlock in these games (due to the cost).
