This may be true, but it is WRONG for the original poster's question:
he asked if you can run an image from RAM  before  birnung  the  SAME
image to the final position in flash.

As you mentioned, many changes are necessary,  and  the  final  flash
image  will  bue completely untested in all these areas then. And one
of these untested areas is the most  critical  in  all  systems:  the
setup of the memory controller and SDRAM initialization.
