Yes, you can do that in Lion. But once you have your windows on screen your keyboard is useless. May as well just start out with a gesture to begin with because you'll have to take your fingers from the keys anyway.
Expose/Spaces in SL has the ability to show *all* non minimized windows and all spaces on a single screen (to drag around as you please). Not so in MC.
There is no 3rd party app that brings back the functionality of Expose and Spaces you have in SL. You'll have to stay with SL or learn to adapt.
I find MC nice for casual browsing... useless for everything else.
