It would involve adding a int64_t an uint64_t types to wl_argument (I'd call them U and I personally) and adding code throughout libwayland to parse them. In terms of backwards compatibility, it should be fine as long as you make it 100% clear that your new protocol extension uses the new 64bit types and therefore requires the newer libwayland version. The other option is that you could do what Pekka did in the presentation extension and split it into two 32-bit parts. What do you want to represent that needs a 64-bit type?
