I'll totally try this out when you finish.
The character swaps from other modders felt so out of place and looked bad in the AVWW world art, and this totally is the way around that problem.
Sometimes, the characters seem out of proportion since they are taken from sprite much wider and shorter than the original AVWW characters(also too short or wide for their hit box), it's hard to tell just by looking, but those small looking megaman characters fill their hit boxes properly?
Nanostrike made plenty of examples of bad sizing, but I'll just use one example, he swapped Jack with a sprite almost half his height.
