Always been into weird stuff.
Know what you mean with the bamboo double guided rod, had one. Never used it,, but found it interesting none the less. Remember the tip was a large diameter and centered over the blank's tip. That would probably be the hardest thing to find now days.
Would think if you used single foot guides, spaced accordingly for each on opposite sides you'd at least have a "conversation" pc.
Reel seat couldbe the plate style, set on opposite sides. Or if you like the "Low Butt" tourney casting style, you could keep both reels on the rod at the same time (hi/lo).
Suspect you'd only be able to have one side rigged and ready at a time.
About the weirdest I've done to date is take a 8' 6 wt. flyrod and had it converted to light spin. Found it to be most entertaining on LMB, tinker macks, scup, and snapper blues.
Then one day I was scup fishing outside the West gap and got hit by a real Bluefish,,,,,,, #[B]SNAP![B]&,,,,,,,, end of story.

(split the top section for about 12") But it was fun while it lasted.
