Have you ever ?

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.

tagger, i understand what you want to do, but the idea is not very practical (2 sets of guides - cast/spin same rod). with the technology of braid and ceramic guides, you can do what you want by having a rod built as a caster, but use at least a size 30 guide as the catch guide and space it out as far as you can from the reel w/o the line touching the blank. then, continue building as a caster, tapering guides down to size 12s. as mentioned, put a reel seat w/o a trigger on. if you want to put the spinning reel on it, turn the rod around. the rod will be stable as the spinner as well. i would definitely tape the guides on and make several test casts to be sure you dont have line slap or wind knot problems. good luck.
