I love your ideas, though I think some of them will be difficult to implement, like the DS version and Nintendo's exclusivity agreement with bringing it to PC or consoles. Adding things from the Chinese versions would mean redoing the work, since there are many inconsistencies in both plants, zombies and scenarios design to make them logical in the first Plants vs. Zombies, but I hope the Replanted team listens to our ideas and that there are people interested in the game who don't want to see it die with a bad reputation.
They should be redesigned, but the Replanted ones could easily do it. If you look at the zombies in the Chinese easter egg, they're from the Chinese versions, and in those versions, the zombies have big heads like in the mobile versions. The Replanted ones remade them to fit, so it's just a matter of them putting in the effort.
