TL;DR version: Nevec makes a walker similar the Bleed to fuse with the  Granseed.

I've been hoping for Nevec to make models of the Bleed and Baylid (similar to the Granseed being their model of the Drio) which would have a different and more streamlined model, a cloaking feature, no self destruct, less armor, and the ability to combine with eachother to make a much more powerful walking VS.

Edit: The bleed-type VS would go on bottom and the baylid-type VS would go on top, by the way. They would each retain their usual controls (minus the baylid being unable to move), but would gain something by pressing Y, just like the Brocakti.

Hell, now that I think about it, Capcom could just use the Granseed as the bleed-type VS that I'm descibing, and only have to make one new VS to resemble the Bleed. Perhaps it could have a permanently fixed laser lance for the left-stick-clicked-right-trigger attack.
