Perhaps heavily encumbered troops could start with some fatigue in "heavy" terrain provinces?

This is a pretty interesting idea, and the type of flavour thing IW favours adopting.

Maybe also easy to implement, same as we have extreme cold/heat penalties to encumbrance depending on province weather scales, we could have some penalties depending on province terrain.

Just should be careful not to make 0-encumbrance troops too powerful from such change.
