Woooh the weevil looks great, and
tiny! My weevils last for ages on batteries, so I wouldn't worry about them running out, they sound cool when they do die, battery starve in extremis!
If you are handy with a soldering iron you could solder the touch contacts to a mini patchbay (like on the rx17) so you can patch the two together. It will invalidate your warranty, and Tom advises against it, but it really opens up some possibilities

That is a fantastic looking set-up, once I get a bit of cash I intend to get some nice new boxes like yours
