Okay, let's get one fact out of the way right now: Crypton is not the only organization putting on VOCALOID concerts.

They're the ones that get the most popularity, not going to lie, most likely because of Hatsune Miku and her popularity. But there are other groups, including fan groups, putting together concerts. Several of these fan groups performed in Japan (such as "NicoNico ChoParty"). There have been several fan groups performing outside Japan as well, although most of these do not feature live bands and cannot be considered complete "live concerts".

There have been some notable non-Crypton VOCALOID characters who have also starred in live concerts.

I personally wouldn't mind seeing derivatives appear in concerts (excluding derivatives just because they are not "the original character" themselves is excluding a good amount of concert material). But it took more than two years before Crypton themselves added KAITO and MEIKO to their concert line-up, so the likelihood of a derivative getting into a concert, even for one song, is probably quite low.
