Has anyone thought of making an R2-D2 model?

I started making one with T3 however I kept running into difficulties with the dome. I was using Taina's replacer tool so I was trying to reposition the vert coords. Since play with the body models tends to messup animations unless there is some secret method that isn't outwardly known I couldn't do much more beyond that. I did release the prototype Body model with either a R2-D2 Skin or R3-T7(Lime green) Skin.

Im no expert but dont you have to reweigh the mesh.
