Seeing as no one else is offering advise on this question, I'll make the statement, yes it will!
I've only made one bow from ERC but it came out quite good.
It was full of knots but it has no crystaling, because I kept the belly quite flat and made the bow long (80in).
I got the stave from the grounds of an old insane asylum thinking it was Irish Yew but it turned out to be ERC which is a Juniper if you didn't know!
