If it's even more to ask(if you already know)a guide for deleting the mesh and reassign the purposed bone struc to any new mesh.
I know 3ds max has tools to modify bone rigs to struc like each other and transfer animation. But for some, with other tools, (Like MED ->yuck!) deleting the mesh adding a new mesh and reassign the verts my be easier.
I've never tried it but it should work without any problems in MED. For example delate mesh and save Tpose of skeleton without animations. Load your mesh and setup it properly on Tpose skelet. Then you need attach vertices to bones.
First go bone mode and select two circle on end and begining of bone. Your bone should be red. Then go to Apply Vertices Mode and select white vertices and click on Apply Vertices. You need do this with all part of body and your mesh will be rigged. Later you can export animations you want to ASCII from old model and import in new riged model.
Btw i not recommend MED for this but it is possible.
