Maybe,
You've expressed a desire to drop the trip. If you travel on Monday, and don't make it, as long as you call CRS early they will have the ability to fill the trip.
A look at the contract answered my questions, lose the pay, lose the bank, no discipline.
8.C.1.e
"If a pilot encounters difficulty in his deviation travel to the
revenue departure location to such an extent that a live flight
is jeopardized, he shall contact CRS at the earliest opportunity.
If the notification to CRS is provided in sufficient time to allow
the trip to be covered by a reserve, and the flight is not delayed
due to the deviation failure, then the pilot will be dropped from
the trip without pay, receive no deviation bank credit for the trip,
and shall not be disciplined."
