A cursory look tells me a pound per rotor may be
feasible.
Any info on this?

Titanium has been tried but I think the thermal characteristics
were found to be less than Ideal. 

I think a steel aluminum composite 
design similar to the rotor housing might work. Better heat conduction
out near the apex seal slots might help cool the apex seal springs 
better. 

A two piece design 3D milled out of steel and laser welded
together on center line might also work.
