Another factor is a forced air system frequently already
has a heat exchanger in it, the AC evaporator. *Adding

ROFL...

Not just cutting it into the duct work and adding it to what
is already there, but modifying the trunk where the AC coil
is located with some dampers and adding a place for the
hot water heat exchanger would do just fine without burning
out any fan motors as it blows the air past the AC coil just
fine without burning out now...

It sounds to me like the OP's idea will have a high initial
cost and would be quite a while before any sort of ROI is
realized...
