Of course you have to match the devices.
Stability issues did not come up, but you are looking at lower bandwidth in the output stage for a given bias current through the input diff pair. For greater bandwidth you can increase in diff pair current by a factor of 2, and if you see any oscillation, you can increase the lag capacitances.
