Yes, certainly, but it's very likely that, adapting plain TeX (i.e. 
plain.tex) to Unicode, people will end up willing to add definitions, 
for example, for the additional math symbols in Unicode, and then for 
the additional letters in it, and finally to adjust, optimize and 
enhance the Plain macros. And then you end up rewriting Omega/Aleph, or 
creating yet another variant of TeX.

That said, maybe that's overly pessimistic, and/or I'm misinterpreting 
what you suggested. I thought xplain.tex did all the Unicode adaptation 
of plain.tex for text fonts; maybe what would be needed is another file 
doing the adaptation for math fonts.
