No, downloadable content for Guitar Hero games is only for the PS3, 360 and Wii. Furthermore Guitar Hero Aerosmith has no downloadable games on any of those systems.
All Guitar Hero Games that came out for Ps2 doesn't support a DLC. so all you need to do is to create your own custom song (IT'S REALLY HARD TO DO ONE) but i can give you a hint.
