Groundbreaking questions for 2000+ players

Hello guys👋

Please suggest opening recommendations that would work for me(≈1900-2000 range). My opening repertoire along with their win rates is the following:

White: Jobava London (≈48%) 

Black: Caro kann(50%) and

Kings Indian Defense(52%) 

As you might have noted, I perform poorly as white while playing the Jobava London system. Any alternatives? I would prefer openings that don't have much theory. I have already experimented with e4 openings but I somehow don't enjoy playing the resulting positions.. I am aiming for an ambitious 55% win rate with my main opening. 

Is my present win rate satisfactory for somebody seriously looking to reach a level around 2300-2400 rapid and blitz? Or is my targeted win rate overambitious?
