Yes, that would be a nice way. However, I'm not aware of such a package,
and Mathematica is so firmly rooted in standard complex analysis that I
suspect this would be tricky. When I wrote "mindless algebra" I didn't
mean Robinson's approach. When I see a package with NonStandardExpand[],
and SameMonadQ[], I'll want to give it a spin...
