It's not beyond modern technology at all. A good repro house could get the photos in a decent state, but the limiting factor will always be the quality of the original printing, which wasn't that great, I don't think.
For the publishers, I think one of the problems would be that the book has great rarity value, but would be less attractive as a new edition, without that rarity value. Given the nature of the routes featured in the book, it is no longer quite so representative of the state of British climbing at that level, so it's definitely a piece of its time.
I still reckon one option would be to make it available as an ebook, with a print option at a premium price.
