There is an out fit that do it on the BA sims and I believe they are all current pilots and you have to do the sim sessions at unearthly hours if you like it or not.
Personally I would leave it just now until things start moving. Your going to be pretty rusty by the time low houred guys are getting the call. The sim time will do you no harm getting back up to speed and saves you the cost of paying extra sim time before any sim checks.
