I want to say that the keys to an HV are always stringified and kept as char*, not as SV*s.
Well, that's just it. There is a provision in hv.c to actually have an SV as the key (rather than a char *). The HeSVKEY_set macro is supposed to be doing that.

A good starting place might be to look at what Tie::RefHash does
I'm afraid that Tie::RefHash doesn't have any XS component to obtain any inspiriation from ;-(
