I can see Grayfia maybe going to Issei on a very lonely night, but I feel if anyone is going to stop that it would be Issei himself.

Perhaps if Sirzechs and Issei didn't have the relationship they do, Issei may not care, but Issei I feel respects Sirzechs far too much to lay a hand on Grayfia.

Ultimately, I feel that if Sirzechs gave him a pass, Issei may do it though. It will come down to if Sirzechs is okay with a little swinging or not.
