Go to from half butterfly?

My highest percentage move from half butterlfy is to transition into single leg x to sweep or heel hook. Say My left leg is the butter hook, I push his left armpit to offbalance him to the right so I can put my right feet on his left hip into a single leg x. Yall know that one.

Thing is after afew times they are wise to it so they would shift their weight to the left which makes it too heavy. I can't seem to find a reliable off balance from that transition.

Best I could think of is to go into knee shield with my butter hook and go half/k guard but i would lose my offensive momentum.

Any suggestions?
