The Avalanche wheels will fit the Monsoon, so it should work backwards. The Avalanche tires are taller than the Monsoon tires, so if you install Monsoon wheels/tires onto your Avalanche, expect more low-speed torque at the expense of top speed. Also expect to lose some ground clearance.

They both have 17mm wheels, IIRC, but I think the Monsoon has more offset? I think 1/2" offset wheels should fit just fine, but I don't have either a Monsoon or an Avalanche to prove it, so this is at your own risk.

Edit - are you asking about adding Avalanche tires onto Monsoon wheels? Ew, I haven't got a clue.
