Will a RB2 Fender Stratocaster Wii Guitar work with Guitar Hero (in a MODDED Wii)?

I have my 4.2U Wii console correctly modded, with USB Loader GX and 4 RB backups (RB, RB2, The Beatles: RB and Lego RB). I've also purchased via eBay a RockBand2 Fender Stratocaster wireless guitar, that works perfectly with all the 4 aforementioned games (I also have a Logitech mic, attached to the RB guitar USB hub, and also works). My question is, I've heard that, in stock conditions, a Rockband guitar won't work in a Guitar Hero game, and viceversa: but what about in a MODDED condition? Note: I use cIOS 223 in my USB Loader with the RB games in order to hook up the peripherals.
