I was contacted by a pro cyclist last year to design some ultra adjustable and hot swappable aero extensions for the wind tunnel.
Unfortunately the timeline and language barrier (and my own lack of ability) kept it from materializing beyond rough prototypes (which I think would have worked fine but I don't think his team were keen on it.)
Roughly, the main body (I could never get exact dimensions of the base bar bolt pattern, so I put a cutout in the design so you could just drill two holes on site, but ideally you'd have a more elegant solution for specific base bar mounting) is "static" and supports majority of rider weight/attaches pad and accepts whatever end is used.
The actual bend/grip section would be hot swappable (multiple pieces) that connected - again in the quick design held by friction but a thru bolt/etc could be used, the idea isn't ultimate structural strength, just has to have some support on a trainer. These could also be made longer/shorter as needed.
In the last picture T-slots are in the body of the bar... allowing you to attach an armrest and have considerable fore-aft adjustment.
Ideally you'd print them in Ti or another robust material. For my cheap "will it work" testing PLA held up printed at high infill (obviously not long term)
Unfortunately, basically everyone I talked to ended up "wanting" something you could use on the road...which is difficult. Original idea was for wind tunnels/fitters only.
