Suggest that the drummer plays keys, the keys player plays bass, and you play drums for the track.
Or try it at a rehearsal, making sure it's recorded.
I'm not sure that the backbone is carbon fibre. The silvery grey edging to it suggests that it could be a piece of aluminium channel with carbon fibre wrap over it.

I can see some issues. Like it might dig into your leg, and the bridge doesn't have independently adjustable intonation but it's done in pairs (I think Telecasters are like this too). Still, an interesting instrument.
The toggle switches got here. I connected them up as per Bartolini's wiring diagram and (without buttoning everything up, just in case) tested it. Silence. Sticking my finger on the series/parallel switches gave buzzes. Putting a scope across each coil of the pickups showed a signal so I thought I'd check the signal across the output from the switch and realised that I hadn't connected the ground side of the pickups to ground. Well, that explained that. I sorted that out and now I have sound.
Obviously I can't now say how the MK1 compares with the BH2s in the Ibanez because the Ibanez has Aguilars replacing the BH2s and the Cort has MK5CBCs replacing the MK1s. However, I will say that the MK1s when I was trying them had a balanced and full sound, not lacking anywhere. Not sure why they have a bad reputation, other than snobbery about made in USA versus made elsewhere.
I did a swap of a pair of Bart BH2s from an Ibanez EHB for a pair of Bart MK5CBCs, which had been permanently wired as parallel. I thought I'd make them switchable so got some 4-core cable and re-rewired them, drilled holes for and connected up the toggle switches, got silence, realised I hadn't connected the pickups on the ground side, sorted that out, and now I have proper sound. Woo hoo.
When I visited @dub_junkie to check out a Bogart that I ended up not having, I had a play on a Klos 4-string that he had. I was rather impressed by it, but I play 5s and Klos weren't doing a 5. However, the website did say that one was coming at some point, so I put my name down as interested and a couple of days ago they sent me an email saying that their first 5 string sample will be out soon, in about a month. Could be interesting (OTOH, could spell the end of my life if I try and buy another bass).

One tuner: Zoom MS-60B - works well for me
One drive: Zoom MS-60B - works well for me
One fuzz/distortion: Don't use them
One envelope filter: Don't use them
One octave: MXR Bass Octave Deluxe - impressive capability
One modulation: MXR Bass Chorus Deluxe - also impressive
One preamp (doesn't have to have DI out): Zoom MS-60B - just for EQ
One pedal that does reverb or delay (or both): Zoom MS-70CDR for reverb
and one wildcard... EHX C9 Organ Machine - who can resist an impressive swelling organ?
No compressor though? TC Spectracomp if we should allow that too.
Also worth having a word with Andy of Andy Charles Guitars in Halesowen - https://www.andycharlesguitars.co.uk/
He refretted my Sei Flamboyant and did a lovely job of it.
