Here at our club, we run unofficial matches during the off-season the last few years; and when (if around here) it gets too snowy or cold, then we run the matches with .22 pistols after the snow flies (Canuck44's idea), no reload stages and limited movement. Use poppers frozen (or otherwise anchored) in place, rather than cardboard. Ya it's not the same, but you can still run different scenarios and it keeps you sharp & the enthusisasm up during the off season.
It is easier to coordinate as well, with the limited set-up and reduced time commitment.
Should add: the reason for .22 RF & no reloads (and no setup), is so you don't have to chase brass and freeze your fingers off. So that covers off the cold & snow, at least in our area. We don't see -50 though...Normally it's -5 through -20 ish.
Only a suggestion. Good luck
