In theory you might get away with a lot of cool mods to support an aero position... but maybe none at all.
Right now you could certainly slip these past an official who doesn't give a crap. But the
spirit of current mass-start road rules is, I would say fairly obviously, to inhibit bars that simultaneously offer a hand grip and elbow support. (Theoretically for safety, but I think also to force aero to require an upper-body effort tradeoff. There's an element of aesthetics and race dynamics there.)
It would suck if this type of bar became accepted without an explicit rule change. If bars offering aerobar-like grips and support are deemed to not be a part of mass-start road racing, these should definitely be banned. And if the UCI decides to back off on that, then they should just throw their hands up and allow aerobars full stop. Whatever they go with, having the sport in an uncertain half-baked compromisebar situation is bad for everyone.
Of course, the UCI being the UCI, they'll likely allow it for a few events and then flip the rules to ban them on the morning of a major race.
