LCA scheduling question...

I'm very junior so don't have the ability to do the LCA bidding out of the gate and work that angle. But I did pick up a white slip with an LCA later this month. Didn't even realize an LCA was on it until I had it on my schedule.

Any idea how often they actually kick the FO off for OE or something else? I'm guessing it depends on fleet (717, 88...more than the 737 or 320...?) and base (NYC...more than SLC or CVG).

Obviously I'm planning on flying the thing, but I'm just curious if there's a real chance of being bought off the trip. Or...is it more in the Dumb and Dumber, one in a million chance of being bought off the trip.
