I have had better than 50% success on honing pitted bores. Less than ideal? Yes. The ones on my 46 were very pitted. I expected to have them sleeved, but decided I would take my chances. An hour later I bleed the brakes and I have not had any issues with them in almost 3 years.
My point is, is that you will not spend very much time or money to see if they will work it and it will keep you on the road.
