you could use these two disk yes.  to get optimal performance you would have
to sacrifice half of the 4G disk.  make a slice on the 4G that is the same 
exact size as the 2G with a single slice on it.  also, have the two drives
match as far as offsets go.  this would get you the same performance as having
two 2G disks.  it would work, it would be fast, however you lose the use of
2G of space unless you make a 2G filesystem on it and only use it for light
loads (storing of stuff, don't read or write to it often, or choose times
when the striped disk isn't being used heavily)

just my $.02
