Yes, that should work... Shame that costs 1/6 of the whole brake set rear/front (found at 300€ now)this works Wolf Tooth Shiftmount | Merlin Cycles the ISEV-ISB one i used on my saints with shimano slx I-Spec EV shifter
So for the Saints the option I used was a bar clamp that mounts to that I-spec ev shifter not to be confused with shifter that comes with the bar clamp. I'll try to post a picture of it by tomorrow. I had to get the correct one for mine and ended up getting one other one before i got one that fits right.
