Yes, but we are already at the limits of cross sectional size.

The challenge on the drive-side lies with maintaining a certain q-factor and providing sufficient clearance for the front derailleur. For MTB everything seems to be moving towards 1x, thus eliminating the need for a front derailleur and crank arm cross section can increase to benefit strength and torsional stiffness.

The non-drive side doesn't have this clearance issue but its stiffness is more dependent on axle diameter. For example, that's why it's downright unwise to try to tune the axle of a crankset by removing material.
