triple booting CM9+CM7+webos can this be done?

I was looking at doing this because even though CM9 has hardware video decoding I am still having problems playing games that ran fine on CM7.

I've heard rumors that the cyanogenmod guys have done it, but it's very difficult to get working properly.

Perhaps have a version of CM7 and CM9 stashed in 'cminstall' folder as 'zips' and just try it.. install via Clockworkmod?
Back up first of course!
