i'm sure you could make them work... but it woudln't be the most practical way of doing it.
i'm not sure what kind of metal the wires are made of, so they might rust.
also, there will be A LOT of play in these, because of how wide the bend is in the wire.
it would be easier for you to go to the hardware store, pick up a spool of 19 guage stainless steel wire, and bend out hook hangers/joints/line ties with that. all you have to do is cut a piece about 1.5" long, put a nail in the vise, bend the wire in half over the nail and use pliers to close the hoop made by the nail.
i made a brief tutorial on making twisted wire hinges (http://www.bassresource.com/bass_fishing_forums/YaBB.pl?num=1221880921), and these work great, but i've come to realize that the twisting isn't really necessary, just bending and crimping them will be good enough. this means if you're following my tutorial, you can stop at step 5 (if you're making a line tie/hook hanger) or you could stop at step 7 if you're making a hinge.
