Guns with grappling hooks?

[Satan From Wreck-It-Ralph]

So I'm currently working on a deathmatch gamemode with a focus on swinging across the map via grappling hook. Except there's one problem - You have to switch from your shooty gun to the grapple gun. Would it be possible to merge the two and have the grapple hook as an alternate fire mode?

probably

rmb to grapple, lmb to shoot
but it could be weird to use

Grapple playertype with right mouse button as grapple?
