Ouch. A Combined figure. This takes practice and knowledge of modeling and CR2 hacking. Modeling would be aligning all the parts and such in a modeler then using (from Freestuff to the right!) compose to piece all of it back together. Then use UVMapper (also in Freestuff) to re-map the figure. After that comes the fun part of hacking the CR2 file. It gets complicated, but you'd need to know how to edit it to reflect the new character body parts and such.
