If you can keep the changes in reasonably small chunks, I think this 
would be doable. Just try to avoid the one-size-fixes-all approach of 
throwing several hundred changed methods at a single point in time.

non-inlined VM would be a much better starting point since it will only 
report each problem once and not every time it trips over an inlined
