they need to pass the size rules. that is they cant poke more than half inch through a 2 inch hole i think. so it would need to be thick and the whole thing would need to be padded as a courtesy surface.
crossgurads arent terribly effective in dagorhir and there is a simple way to do them out of just foam. they look good. with hands on weapon already being a no go shot theirs little need for a cross guard, except for ornamentation. and the foam ones do that well.
