No, you don't need to touch your file1.tex, just change your main.tex
where you reference the external labels.  Maybe letting RefTeX reparse
your main.tex helps?

Yes, it seems so.  But with the optional argument in \externaldocument,
`reftex-reference' will prefix all external labels with A-, so the
workflow should be easy.
