My Frankenbike drive train would still be a Tringle-speed with a Shimano front pull side swing front derailleur (you should try one, they shift as well as the best rear shifters) and an old Campagnolo Record of Huret Jubilee rear derailleur with just one cog, like a Singulator encase you are running dual suspsension.
With just one friction shifter. The spring direction from the front and rear derailleurs work in opposite directions and the forces would cancel each other out. Maybe using some kind of Y pivot mounted just ahead of the front derailleur
Hopefully some of my old Cycle Dynamic individual Ti cogs could still be used (easily under 150 gm maybe 180 with aluminum spacers.
Purpose would be for bikepacking where you go from having to backpack your bike 38km without the tires touching the ground, 2 hour long 25%+ climbs, to hour(s) long rail grade downhills or plateau/prairie backroads with a tailwind
