Can I re-bundle e-gadgets for a different battery?
Edit to clarify that I'm not keeping the GoSwiss motor. Any new battery would be just for the lights and brakes.
I bought a 2014 HP Velotechnik Scorpion FS26+ with a GoSwiss motor. My plan was to replace the defunct hub motor with a regular wheel and call it good. I've since discovered that the trike has internal wiring for front and back lights as well as Tektro e-twin hydraulic front disc brakes. All systems were designed to plug into a battery that I don't have and which is no longer made. Is it possible to re-harness the wires to plug into a different battery?

Without a lot of detailed info on the bike, I doubt that anyone can give you a simple answer like "go buy this battery and plug it in".
In principle, you should be able to build a battery pack of the appropriate voltage and connect it. It looks like it has a fairly standard automotive connector on the bike, so you could buy a mating connector from an auto supply store. I get the feeling that you may not have the technical skills for all of these activities, though.
It might be easier to just remove the lights and install new ones.
As for the brakes... I'm not familiar with brakes that need electric power. Is that just to activate a brake light, or is it more complicated?

The brake lever "power cut-off sensor" according to the Tektro site is a normally-open switch. If it's not running a brake light, you don't need to plug it in to anything. I found some documentation that implies this controller does not have a low voltage take-off so it would be full battery voltage for accessories. But that's 36V. Which is a big number to be wrong about. Some lights that take high voltage then have a lower voltage take-off from the headlight to do lower voltage tail lights. Can you figure out the brands or models of the lights? Do the lights plug into the controller with controls from the head unit? Or did they plug into the battery with their own switch?
