Hi, person working on the summon mod here.
I like a lot of these ideas, most of them are currently possible to my knowledge. Back views should be entirely possible with outfits or even expressions. My hope is that we get a way to implement “scenes” which are illustrations for specific scenarios, which could potentially be possible by using expressions, but would be difficult.
I tried my hand at converting unit’s teams for the AI vs AI feature, however currently I do not believe it’s possible for a unit’s team to be changed after it’s created and it’s AI behave properly.
Evolutions would be interesting and would entirely depend on the extent to which they affect the unit.
AoE is possible, all it needs is a unit who does it.
As for Size changes, I don’t really want to think about the nightmare of programming that, I don’t think it will happen soon.
I’ve been working on implementing the new mechanics I’ve been working on into a character who can augment her body during battle and utilizes a resource system. Won’t be done for a while due to art but so far it’s impressive what’s been able to happen with the existing code.
