Not only is it possible, that's one of the best selling points of shooting LF. It's very easy to keep a spare shutter or two in your kit. In the unlikely event one spontaneously goes kaput, simply unscrew the front & rear elements from the faulty shutter and screw them into your spare.

As for determining the size shutter, I'll try to post a link to S.K. Grimes' chart.

Hope this helps.
