Some good thoughts there. Obviously, a gasser is designed for a
little engine compression braking, so that amount should be safe. You
could also have regen ramp up from 0 to max in the first inch or so
of brake pedal travel, and then ramp down to zero from inch 1 to inch
2 as the mechanical breaks engage.

You could also wire the "low trac" warning into regen disable, so it
doesn't work when the antilock brakes are engaged.

Some trucks have a brake proportioning valve that gives the rear
brakes more pressure as the load gets heavier -- perhaps this could
be adapted to a regen system to balance the braking.
