I can't really see that happening. I have always thought that the overall storyline of the prequels (Qui-Gon taking Anakin under his wing and rescuing him from captivity, Palpatine orchestrating the war from both sides, Anakin turning in a desperate attempt to save Padme) was really good, and that the main flaws with the prequels were the terrible dialogue and direction and the overuse of CGI. Like you I don't outright hate them as much as a lot of people seem to, as I was also relatively young when I first saw them, and was impressed by the fancy lightsaber duels
I think realistically if Disney were to try and re-make the prequels they would change too much, if that makes sense. Yes there is great potential for improving the writing, acting and action, but if they were to make dramatic changes to the core story as described above then I have serious issues with that. There's also the issue of re-casting and replacing those actors in the prequels who were actually good. I can't imagine anyone other than Ian McDiarmid as Palpatine, for example, same applies to Christopher Lee as Dooku (if the character of Dooku would even exist in a re-imagined version) and Ewan McGregor as Young Obi-Wan. It's not a hopeless cause, however, as the recent Planet of the Apes movies have proven that it is indeed possible to make remakes/reboots that are actually good.
I think kids would continue to watch the existing prequels, even if only out of curiosity, just to see if they are really as bad as people say they are. Keep in mind that the prequels were aimed more at kids (hence JarJar), which presumably would not be the case if they were ever remade.
