I think you can if you create a slice on the larger drive that is equal to the size of the smaller drives (so 300GB)
If you just add the whole large drive to the pool, you will lose the extra space. **Apparently if you later replace both of the smaller drives with 2 500 GB drives, the pool should expand. However, I can not get this to work (the pool stays stuck at the size of the lower drive). Others report success.
