Geometry is open and free to optimum design. Gas generator or
otherwise, the criteria is simply steady thrust of about 40-lbf for
about 10-min. I cannot figure a reliable way to make that happen with
any solid formulation. Help?

Does geometry matter like diameter, frontal area? As mentioned before on a
similar topic, I would configure such a beast as a gas generator.
If geometry didn't matter I think it can be done w/o too many issues.

Suppose you were assigned to design a long-burn, low-thrust solid
propellant motor with these characteristics, what would be your grain
configuration, case type, and general formulation:
Burn time 10-min (600 sec)
Nominal thrust 40-lbf at sea level
Operational use <10,000-ft elevation
Would your grain design keep thrust within +/- 10% of nominal?
