Some guidance in the form of an LC-PCC PS would certainly be helpful.
RDA doesn’t say what to do, but it’s pretty clear that in the two AAPs you cited that “Skip” and “Slim” are not middle names. I just don’t think that the person’s intention is to treat those nicknames as middle names. They are variant first names. I would have treated them as such:
UF Miller, Skip
Pickens, Ryan, 1972-
UF Pickens, Slim, 1972-
I think we should bring back the LCRI that didn’t get moved into the LC-PCC PSs.
I’d follow the pattern used in these RDA AAPs:
Miller, William “Skip”
Pickens, Ryan “Slim”, 1972-
I don’t see anything in RDA that says to ‘deconstruct’ the elements of a personal name and prefer some elements more than others.
Of course, ant variety of VAPs might be added.
That's what I would do.

I can't find any guidance for dealing with a name that appears in source as, in this instance, XJ 'George' Bailey. Perhaps Bailey, XJ with a 400 for Bailey, George?
