For sure you can.

If you read the manual you'll see, that the vector table can be relocated 
from
flash to internal ram (and on the 22xx types AFAIK) to external flash (or 
CS0).

Internal Flash is AFAIK with MAM faster or at least as fast as external 
RAM .

A customer of my companie does 2) and 3) on a 229x with success.
