Not a bad idea. You'll work more like an Archer on the battlefield but that'll be cool to see. And yes, if you can send me pics I'd really appreciate it. 
So every Class (more or less) has things they need and things they don't need. In case for Tinkers, Attributes don't matter nearly as much. Tinkers will mostly need high Skills. Although Agility will decrease their reload times. As for dealing with cost for early game, I'd suggest taking your shots carefully. Let your friends take care of weak minions, go for that high-damage shot on the boss or something.
