Sorry, I didn't see that. I thought he was just asking if u-boot could be modified to run from ram...

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.
Best regards,
