This is what I thought the inside could look like, equivalent in size to the other wild burro hinged baffles. I envisage this having plants and pictures on top, but maybe it could have a grill. Can you get pretty patterned acoustic neutral fabric?
How would I make it a labyrinth, is the betsy suitable for TL?
An externally hosted image should be here but it was not working when we last tested it.

Well, countless console stereos were built with pretty much that same layout. No reason it wouldn't work as sketched. I would suggest lining the inside with some carpet felt if it's going to be near a wall.
If you wanted it to be a labyrinth - first guess would be to close the back, add a center divider to make a simple pair of one fold TL pipes. Add an exit to the bottom. Oh, and replace that triangular center reflector thing with a simple board. I don't see any reason the Betsy wouldn't work in a TL.
Just guestimating from your sketch, I'd say you'd end up with about 3 cubic feet per side, and maybe 48" long lines. Perhaps you can talk someone into running a sim. I'm not set up for it at the moment.

Quicky, why have i never seen people using the wall as a baffle;
Suspended from a picture rail, with the wall becoming an infinite baffle...

I do this all the time with my wall mount speakers: Cornu, flat BIB or FIB, flat stereo MLTL, and folded MLTL. No baffle step loss and no floor space needed. Lots of advantages.
...not quite right...it would only be an infinite baffle if you incorporated it in the wall, as one part of the wall would be facing forward, one back
the way you showed it... is like small leaky box with back wall close to the driver...you may not like the sound of it, as it will likely have poor low fr response and ton of back reflections re-radiating through the speaker...
just my opinion
I have tried a MJK style OB with an Eminence 15A as helper woofer. Without a helper woofer the bass is just too weak for my taste. I used some surplus MDF, a miniDSP and bi-amped using 2 Gainclones. Betsy required quite a bit of equalization to be somewhat flat.

IB is basicly like a very large closed box
infinite means that front and back cannot couple acousticly
wall mounted is very far from being infinite baffle(IB)
small closed box would be closer
but the trick of IB is very low bass, so ...
but if you call it a small box with very big baffle, no objections
that at least is explainable by giving the needed acoustic BSC support
