Hey man, what's your proficiency with coding for RPGMV? I talked to GALV about possibly adding a few features to that projectile plugin, but he doesn't really work with RPGM anymore. He suggested I look to some other people to potentially adding to his or creating an all new one.
If the new RPG Maker's character generator produces full busts and can match the art styles of previous RPG Makers, that might be a big incentive to buy it. An easier way to craft custom map tile sheets though would probably be an even bigger game changer.
