Isn't that the way we use MARC 7XX$a$t now, with the relationship in a 5XX note? Field 740 has 2nd indicator "2" to distinguish an analytic from a related work, but not 700 or 710 $a$t.
More or less, yes.
The relationship subfield you suggest would be something new. But to me, such entries for related works/expressions/manifestations would more at home in MARC 7XX than 6XX. The same authority can serve as the basis for either.
That's what I mean. B.E.
