I just built a V2.2 and I covered the fuse with lightweight silkspan instead of 'glass. I'm happy with the results and it saves about 2 oz. vs. the 'glass on the fuse alone (not counting paint + primer). By all means take your time and let the dope dry about a week (at least) before you prime it. You want to use Nitrate dope to attach the tissue NOT Butyrate. Nitrate dope shrinks less and bonds better to the wood and fiberglass (cowl). You can get Nitrate dope from Sig. It's not fuel proof - but you're going to apply paint on top of it so don't worry about that. You'll use a lot less primer than you would with glass because the silkspan is prety smooth. If you do it right, you may even end up lighter than a Monokote finish but you have to be REALLY good with the paint. Don't expect to see that with your first silkspan job although you might surprise yourself. Weigh everything as you progress so you can see where the weight comes from. That way you can try to do it better the next time.
