Help with htr

[Bttyx]

So I need some help from you guys, say I am in a position on a 2x2 where all the corners are orientated, how do I turn the cube into htr state and how many average moves would it take?
Might make a FMC method with this

You are basically trying to adapt the 4-phase Thistlethwaite´s algorithm to a 2x2x2 cube, at which point I would recommend adapting a 2-phase algorithm instead.

You are possibly looking for these algorithms.

If you look at this post, you may find other details for both Kociemba´s and Feather´s approach.
