A total vfx remastering would be infeasible, I think, unless they did an official Prequel Special Edition. Haha.

Maybe if there were more specific things that were addressed, it would be easier for people to tackle them.

If I had to suggest one thing that needs to be played with vfx-wise, I would go with the first deleted scene of Padmé from AOTC, where she is addressing the Senate. The vfx were clearly not 100% completed, because it looks pretty crappy compared to the Senate scenes in TPM. Even the “Senate chatter” sound effects sound like placeholders or just incomplete.

I think some of those shots just need to be replaced by some Senate shots from TPM, improve the sound effects, and maybe do a few other things to it.
