I believe all this is possible but I don't know how to get started. Can someone point me towards a good resource?
Step 1) Unscrew the screws to separate the the case halves.
Step 2) Remove the back and unscrew the 4 screws holding the plate/hammers/caps to the top of the case
Step 3) Remove the screw holding on the PCBs at the top
Step 4) Carefully bend the tab near the screw that holds in the PCB
Step 5) Remove the plate/hammers/caps assembly
From here it's a bit tricky. I couldn't remove the plate from the assembly without a hammer so I couldn't do what phosphorglow shows in his video. He removes the plate then tapes the hammers on a piece of tape, one per row, so the hammers don't all fall out. I did it the hard way. Put the assembly on the side, got the plate off, then all the hammers fell out and it was a PITA to reseat them all. You can try putting the assembly face down, removing the plate, and then taping the hammers them pulling them out. Watch his video if you're not sure what I'm talking about.
Once the plate is removed, you can move the hammers around to accomidate the layout you would like. When you're done, do everything in reverse. It's not too hard. If you don't drop all the hammers out, it's a fairly quick mod.
If you have more questions, I can take pictures.
