I don’t think foam rolling should replace stretching. From an anatomy standpoint, foam rolling and stretching are targeting different things.
Foam rolling only really impacts the superficial layer of tissue such as the skin and fascia. while stretching (if done correctly) works on a totally deeper level than that.
So to give up on one or be completely sold out to one over the other would be unnecessary.
Now I think you could spend less time doing both of these and from a chronic pain perspective you may end up feeling better depending on how much you relied or THINK the tool was actually helping.
So my final answer would be to keep both if you enjoy them as a part of your recovery. If you don’t do one over the other and your getting along just fine I wouldn’t add anything else that would increase the amount of time you spend away from your friends and family.
