Fuse 2 meshes together ?

I have a real simple box character of a poly count about 2000." looks all full "
The only purpose this mesh serves is for the rigs in C4D.

I send the 2000 polycount box character to zBrush.
I DynaMesh the character ,raze the topology to a million & make it look descent.

Now I want to fuse the million polycount zBrush character on to the real simple box character of a poly count about 2000 for C4D rigs.

How do I do this ?
Thanks a lot.
