" Gain directly depends on it."
No it isn't.
The mu of the tube changes very little no matter what you do.

Lowering the plate load resistor will limit the max output swing but will not lower the mu (and therefore the gain of the stage) at all.
Edit, I should have said "will not lower the mu enough to make any real difference"
