I think one of the cooler mods that you can do to this is rewire the left spacebar to be a backspace key or whatever else. Basically just put a nic in the original traces with a dremel and wire in parallel to the switch that you want it to be the same as. You can always bridge the nic to restore original function by scraping off the solder mask on both sides and soldering or just wire it up in parallel to the other space bar switch on the other side.
