Those bars look very, very good!
My first thought also was lever length, the Shimano hydro ones come in a trekking version (bl-t), which is way nicer on bars that point this much in your direction, because you can move your hands more.
You can get them more parallel than in the picture with the adjuster screw. Loved them on a town bar.
Bl-t8000 seems to be the current version, probably impossible to find without calipers.
That's why I figured it should work.
The two finger Shimano levers might be a bit short on those bars, hard to tell without fitting them but when I've done similar set ups on swept back bars and the like we've tended to use something with a longer lever blade BL-MT200 are cheap AF and fine or BL-RS600 are apparently ultegra level, looks like neither have servo wave but the RS600s use i-spec if you want to attach your shifters directly to them.
