I may be misunderstanding something in the argument, but this potential solution is I think already discussed in detail in Reasons+Persons, where Parfit introduces the repugnant conclusion? He calls it the ‘lexical value’ solution, I think? And I don’t think this write up addresses any of the strong arguments that Parfit makes against it there?
In Parfit’s original argument, he doesn’t just rely on an appeal to intuition that B is better than A. Instead we move to B from A in two steps: first we go to A+ (more people having lives just worth living, but original population unaffected). Parfit claims that A+ is not worse than A. And then we move to world B, where we are now significantly increasing the welfare of already existing people, with only a small drop in the welfare of the original population. Parfit claims that B is better than A+.
If we reject that A+ is not worse than A, then we have to say it is sometimes wrong to create new people, even if their lives are worth living. This seems very strange. If we reject that B is better than A, then we have to believe that a small drop in welfare for people whose welfare is already very high can outweigh a large increase in welfare for people whose welfare is very low. This is the bullet that I think the lexical value solution bites?
But this is a tough bullet to bite! It is the opposite of egalitarian. It says we should prioritise changes in the welfare of already existing high welfare people (whose welfare is above the lexical level) over changes in the welfare of also already existing low welfare people (welfare below the lexical level).
