Not so keen on that idea.
You can always trim (within electric trim range) in the same direction as control column deflection:
Control column actuated stabilizer trim cutout switches stop operation of the main electric and autopilot trim when the control column movement opposes trim direction.
... and ...
Stabilizer Trim Override Switch
OVERRIDE – bypasses the control column actuated stabilizer trim cutout switches to restore power to the Stabilizer Trim Switches
NORM (guarded position) – normal operating position
So there's a "control-column-actuated-stabilizer-trim-cutout-switch override switch". In case you want to use the control wheel trim switches to trim opposite your control column input.
