that would be something really cool to have; I agree!
My mum is all crafty and such but unfortunately not with beads...
But I don't really have an answer to your question; I just know I have seen them before, also online, made with little metal hoops and beads and such so I would think that in general it will work.
Maybe to be on the safe side, your mum might try to tuck away the ends under a bead or charm or pay extra attention that where the wire ends meet, they are lined up so they have less chance of catching on anything.
just my two cents though, since I haven't actually made any myself.
