I am thinking about pushing a Segwit patch to Bitcoin Cash github. Any chance it would be approved on time before 1 Aug?
You can try. I'm guessing you'll be met with an overwhelming chorus of NAKs.
Damn Bitcoin Cash Core ! They want to control everything! They are stopping real scalability for their own benefit!
Hahah.
On a more serious note: There are several other mechanisms that fix malleability. There is still a discussion to be had as to whether or not SegWit is the best approach.
