I'd probably only focus on doing mods that would prevent possible damage--like the fuse magnet mod on TAF (to prevent a magnet locking on and buring the PF); or the drop target coil mod on STTNG (to prevent driver board damage in the head & in turn the diverter coil on the subway frying--if the thin wire ever breaks off the drop target coil).
But if your TZ ever starts resetting, you know where to start.
