Ben, I would be interested to see your modifications.
I had the opportunity of inspecting one of these up close and as super cool as I always thought these were and ALWAYS wanted one, I was completely put off by several things, which in fairness, you seem to be aware of already.
To use these, you must remove your existing engine lid. Fine, but these typically are screwed on to little L shaped brackets down along the sides of the rear window, over the inspection panels. Its a nightmare, just to get at the engine, you need a screw driver to remove 4 bolts and lift the whole thing off, put it on the ground, don't lose the bolts etc and then reverse the process.
Then there is the rain/water situation. Water pours straight down on to the engine.
If you can sort these two issues, you have an amazing product. I would love one of these if it could be popped open like the OEM lid and raised on a hinge and gas struts and use the existing catch. I imagine you would need to add some vanes inside the vents to direct water to run down and off the cover on to the boot lid.
Very interesting, keep us posted!
Good luck.
