I don't really think you have to change the breed, if you made some changes similar to this example (below) then it would be a little more gopher-like. Also the ears should be less like a human and more like a mouse's: very thin, kinda rigid and flexible, and sticking out a bit. Simplified a bit: Less attached to the head, more sticking out.
