[antir-heralds] style/CC: sword within wings

[Ursula Georges]

A client of mine would like a device along the lines of

Gules, a sword inverted argent within a pair of wings Or.

Here's his rendering of what he wants:

Is this reasonable style?  Can you fit a sword between a pair of wings 
like that?  Is it OK not to conjoin them?

(A conflict check would be nice too, if anybody's up to it, but I'd like 
to sort out the style issues first.)
