Clearly: IF the clutch pedal is 'low' ONLY when cold. It has to be the clutch hydraulic device.
So the clutch itself ($$$$) is NOT an issue.
Ir is only a hydraulic device which the pedal compresses the hydraulic fluid to press the internals of the clutch.
It can be the part at the clutch, or at the pedal. Either way it is not a lot of money.
$100 $200 most
You have my sympathy for your wife riding the clutch pedal, and for all the bad slipping and such, but this is just a small issue.
The hydraulic device uses "O" rings for sealing. My bet is one of them is leaking just enough that after sitting, the fluid is all past the ring. with a few uses, it is sqeezed back, and does not leak 'enough' to cause problems while in use.
So it is 100% some leak in the hydraulic device which operates the clutch
A rebuild or new one will do.
