I wanted to do the same thing and I saw this :

That's exactly what I'm looking for. Unfortunately, the reviews are anything but good.

Is it a current gen Aeroad? If so, not sure you can make anything not from Canyon fit as they have that proprietary carbon quill design.

Yes, it is Aeroad CF SLX 8 Di2.

Canyon itself sells a handlebar for the Grail that fulfills many requirements. Unfortunately, this is a Grail handlebar with flair and the 800€ seems quite expensive to me. I have already asked the support team whether something like this will be available for the Aeroad in the near future. Unfortunately, the support team was unwilling or unable to provide any information.
Then I'll probably have to keep looking.
