Yes you can. I wouldn't pay extra for the 1GB however as it will function as a 512MB card. Consider it like raid/memory. It all has to move at the slowest speed.

Yes Its possible
but I wouldn't suggest 1 GB memory. eventually It will be waste of money.
I think, 512 mb memory will enough for CF...

Yup, you sure can.
It will run exactly the same as a pair of 512Mb 4850's in CrossFire.
The extra 512Mb of RAM on one card will never be used.

Well that depends on what he is doing. In my SLI setup I run my BFG8800GTS 320 in the first slot which runs at its full settings. I run my EVGA8800GTS 320 in the 2nd slot because its alittle slower but I use the EVGA one to do all the PhysX. I dont use SLI in most games matter of Fact I dont think I use SLI at all. ha ha. I did notice that useing the fast card I get better Frames than the slow card in the first slot.
