I doubt they’ll offer them 737 slots.
At the moment those LHaulers approaching 65 can’t rely on a 737 slot to keep going.
If there isn’t one there they can’t take it.
I bet the company will want that demographic to take the VR package.
Especially seeing that most of them are on the 74 and 380.
The bigger issue is how long can they keep them stood down.
I doubt a reasonable person would expect that to be three years?
