The Dr Wu one would be ideal but it vanished a long time ago now  

 

And what about Wheeljack's?

Or maybe modify this one: Matrix Workshop M-09B M09B Melee Weapon Set (Sword & Bow) for Female Autobots Combiner Orthia (Elita One, Moonracer, Lancer, Firestar, Greenlight ) Upgrade Kit

 

There's a bunch of staffs on Shapeways for MOTU figures that will probably do the trick, I'll most likely get one of those next time I'm ordering

 

Or that.
Btw how much is shipping on Shapeways? I haven't ordered there yet but am highly considering it.

 

IIRC these days economy shipping is 10 euros, so you're best buying a bunch of things at once.

Please don't buy all of them, I'm going to need one for my eventual Tyrest, too
