I don't quite understand what you mean by 7/8 and 1/8. Are you saying that all of the images have an underdeveloped region to one side because you didn't fill up the tank enough?
If so then the first thing is to pour yourself a tall, neat glass of scotch.
Assuming that you didn't provide enough developer and got a thin band to one side, then I think the main options, in terms of wet processing, are to use a reducer to try to reconcile the thicker portion with the thinner; or conversely, to try to build a bit more density into the thin parts with KRST. But I doubt that either method is going to equalize the two portions in a contrast-consistent way and it's going to be hard to snatch fromt he treatment at the right time. So I'd be inclined to consider (1) creative cropping, (2) dodge and burn in printing or after scanning the negs and working in photoshop....
Of course you might just print them and see if dodge & burn is sufficient. If you print in such a way that the thinner highlights are at the edge of your paper curve then maybe you won't see that much difference.
(Again this is assuming that I understand what you are saying...)
