In some of our rooms we decided to do away with carpet and put down oak faced engineered flooring. It's available in different thicknesses, so you should be able to select a combination which equals the depth of the old softwood boards. As a sub floor, 9mm ply is enough, well screwed down, followed by underlay and the hardwood floor laid floating.
If you do this, buy all the plywood at the same place - I found there was a lot of variation in thickness for the same nominal size. You'll need to remove and refit skirtings, unless you don't mind a planted on bead to cover the expansion gap.
Or indeed, there's some good solid hardwood flooring around.
If you do replace the floor, you may be able to sell your old boards. Old 'characterful' wood seems to still be fashionable in shops and cafes, but as you are finding, one house room won't yield enough, once you discard what has been ruined by old plumbing and electrical work etc.
