Like Red said, it'll work.....but.......make sure that snap swivel is a duo-lock or a coast lock.....don't use those other snaps, they are not very reliable unless you crush them down with a pair of pliers, and then you lose the reason you have the snap in the first place.
That being said, you are better off using a barrel swivel in that postion. If you really need to change to wire, have wire leaders with barrel swivels on the top end. Then just clip off your mono leader from the main line above the barrel swivel and retie. It really only takes 30 seconds or so.
My other thought, as I have said many times, fish finders are okay from a boat, bridge or pier with water running away from you, but from the beach, a hi-lo rig, or a similiar set up with just a single hook, I think, is much better. Because it is more streamlined with the sinker at the end of the rig, it casts a whole lot easier and farther.....and you get less casts-offs of bait. Using a fish finder, when you cast, there tends to be a "whipping action" of the hook and bait around the sinker, which shortens the cast and can cause the chunk or whatever to go one way, while the sinker and the hook go the other. Just my $0.02
Not that the fish finder won't work, I just like the other rig better.
If you are at the show on Saturday, we can meet up, and I'll show you what I'm talking about.
Good Luck!
