Very difficult to tell without more details. But I can certainly conceive a similar hardware that won't fit on the MIST. If you have many subsystems each one accessing its own RAM or ROM at the same time, you might have a problem. As long as you have enough internal RAM it's ok. But otherwise, external DRAM might not be able to reproduce the behavior.
You can access only a single external RAM address at a time, and DRAM (contrary to SRAM) has a substantial latency for random access. MIST DRAM has a much faster bandwidth than old school memory. But depending on the case it might not be enough to compensate.
