I'm pretty sure getting the heat transferred to the coolant by a purposely designed heat exchanger and then having the coolant circulated works better than just sending back hot exhaust gases in the combustion chamber. Plus you wouldn't get the same NOX reduction.

Although the EGR cooler isn't designed for the purpose it does take heat from exhaust and puts it in to the coolant.
