Today, one of my female shaft-tails died (I believe she hit something or got caught on something

Unfortunately, she was the male's mate, leaving me with two hens and one now un-bonded male.
I thought I would re-introduce him to one hen at a time and see if he showed in any interest in one of them, so that I wouldn't have to house him alone.
He showed interest in my deformed hen, Blotchy; however, she wanted NOTHING to do with him, and it devolved into her panicking if he so much as landed on the perch near her. Since the other girl probably died due to knocking her head on something, I do NOT want any panicked flying going on. So no go there.
He then got into a knock-down-drag-out finch brawl with my other hen, Devil. There was beak jousting, harassing, feather plucking, etc. I pulled her out when it got to the point where I was uncomfortable and definitely feeling like it was more than the "establishing a pecking order" phase. So that was equally no good.
Now my hens are back together and looking much happier for it. But the male is alone. I have no idea what to do.
Should I put him in with Blotchy and hope she calms down, then get another friend for Devil? Or should I find someone to take him, and start my transition to more passive birds much earlier than I expected?
These finches are turning out to be the most stressful and heartbreaking gift I have ever received.
