I’ve had no problems grafting Plums(Asian) and Apricots onto Peach(Nectarine) root stock.
The only thing is,Peach may not last as long,compared to a Plum or Apricot. Brady
Apricots on peach roots are pretty common (although I personally think it’s not a good thing to do for a number of reasons). Peach on apricot was reported to have long-term incompatibility, i.e., the graft might take at first but will eventually die in a few years.
