Wabi Thunder with your own IGH wheel. They won’t be back in stock till October though.
Not sure why you’d want a shifter where most people would want one of their brake levers, but it’s totally doable.
Were I your Shop Guy, I’d be begging you to, for safety’s sake, have the bar ends be brakes only and stash the shifter inboard near the stem.
[edit] if you intend on using the bars like they’re mtb straight bars plus barends which you only occasionally use for sprinting/climbing, I’d still argue to stick the shifter inboard between one of the levers and the stem as out on a bull-end is a great place for easily bending a thing you don’t want bent.
