Can I use Wii Rock Band drums via MIDI to directly input into a Korg Triton Pro?

I'd like to load up one of the drum kit presets on the korg and map the drum inputs to specific notes, so the drum kick drum plays a kick drum sound etc... I'm hoping this is somewhat standardized so it's just plug and play.

I have a full Pro Tools studio, and some other gear that I'm sure could serve as a MIDI host, but I'm doing this to let my kids mess around, and I'd rather not involve all my other gear and computers.

Feel free to just tell me it's possible without additional help, or just tell me that's not how MIDI works. Detailed instructions would be nice tho ;) Thanks!
