Looking for advice for my IT commando build

Hey folks, been working on a commando lately and hes sitting around level 50. So far so good. The idea is to use the deadly momentum buff from cadence in addition to other bonuses to IT damage to boost grenado damage.

Here is the grim calc I’ve been aiming towards at the moment.

GrimCalc - Commando (Phys/IT)

I guess my first question is is this a viable route to take? Second is what, if any, devotions should i swap (looking at owl vs. throne in particular)? Third, is this type of build (phys/IT commando either 2h or 1h) viable for farming in ultimate/crucible?

Thanks in advance to anyone willing to take a look at this. Really love this game and this is my first commando (or any soldier really) so I could definitely use some guidance.

EDIT: There should be 1 pt in fighting spirit. Oops!
