Convert Octogenesis to Genesis 2?

Shortstuff81000

Is there a way to convert anatomy (Octogenesis for G1) to Genesis 2 (Aiko 6)? Fit to pinches the tentacles halfway down, and there is the little problem of the lower body still showing, too.  Is there a better way or a product I can buy that will do it?  I use Genesis 2 more than any other figure, so advice for fitting any anatomy parts from Genesis 1 would be awesome!

I dont know the product but looks that the only way is to use the geometry editor and manually hide legs and hip

and manually adjust the tentacle bones

 

edit: i mean not the only but the easier :)
