twin-linked goodies

so if you take the salamander's specaial character from c:sm all varieties of flamers and meltas count as twinlinked

noa, my question, how could i represent this on my models?
so far the only way ive thought of would be to whack on another barrel of said gun's type, e.g. 2 melta gun nozels on a melta gun

only thing is, this could look like a multimelta and multimeltas would look a little busy

so, agian, how you you represent these guns being twin-linked?


p.s. holding 2 of said weapon would look a little hollywood and cheezy XD
