I know 380mm RB-021 is essentially too small to fit my already-small hands. I tried to fit "one" lever on the roof, but it was horrible. Two is too much.
Perhaps you can try it out with 420mm RB-021. That might work, but it would look rather unfortunate with two levers.
I also tried Profile Design's TT-levers on my RB-021. That worked. But you will need to be careful, because some levers don't fit because the first bend is too close to the bar end. I think you will do good with an older road lever strapped on.
