Seems possible.

Anyone tried it?

Thoughts?

GUESS:

slack chain is at the bottom and I suppose the place it's most likely to misalign is at the back - i.e. after it's had 15 inches or so of wobbling about before it reaches the back cog

conventional tensioner "controls" the chain at the back, where I think it's most necessary; yours will control it but quite a distance further away. I bet it's moderately effective at least (my mate uses a vert dropout frame with no tensioner and the chain flaps about like hell but hardly ever falls off - it's a "proper" unmachined ss chain and I think that matters quite a lot

IMO IANAL YMMV HTH GSOH LOL

assuming you mean one where the pulley is under the bb then yes, they work. the only downside I found was that over time or if you caught it on obstacles it'd bend or lose tension.

This could be what you're looking for. Much better looking on the bike IMHO.

I like that ETR-B tensioner. I expect a hanger-mount would be lighter but the BB mounts do look good.

Sweet. Thanks.

Just figured it looks a neater solution than one of those tensioners hanging off the back looking like a spare part.
