You can always fit a Bigsby B5 to one and change all that! Worst I've seen is the non-string-thru Bigsbys on your average Gretsch. You have to thread the ball end of the string over a tiny peg which is on the _bottom_ of the bar, wrap the string around the bar, and then thread it through your tuning peg without it popping off at the bridge end. It's a nightmare - some people use a wedge of rubber or polystyrene to try and wedge the ball end onto the peg until the string is at decent tension.
