I doubt it. Even if you somehow can trick XeTeX to accept the
persion numbers, parameters must be numbered consecutively. 

(\def\test#2#3{abc} gives the same error you got). 

This means you wouldn't have only to add the persian numbers to the
list of "numbers" for parameters, you would have to replace 1-9 with
the persian numbers -- and I don't think that this can work without
side effects.
