If you do play in relatively stable climates, you can always do what Yamaha do on their YPC-32 piccolo G# keys and fit plastic spacers or shims to take up the slop between the ends of the key barrels or rods and the pillars or adjacent key barrels if they share the same section of a rod screw.

A low friction soft plastic like polythene tubing can be cut into shims or spacers easily by mounting it on a steel rod mounted in a bench or lathe chuck, setting the motor in reverse and trimming each shim or spacer using a sharp scalpel which will leave a clean cut and no waste.

I use small teflon shims cut in this manner (fron teflon tubing with a 2mm bore and 4mm outer diameter) to take out end play on sax rollers, but it can be done with keywork if you want to. The only downside is when the keys are removed, the shims will inevitably drop off, end up lost or mixed up unless you (or whoever fitted them) know they're there and can keep them in some sense of order in where they go.
