There's also a threat that the 1XX could be repeatable in the future which would create potential confusion.

We poked around MARC Authorities and came up with 024 (Other Standard Identifier) as a plausible solution by using a $u. It could look like this:

024 8# $u http://example.org/foo

I would argue that the spec for this new $u should be explicitly worded to mention "Linked Data". Sensible behavior would be for it to lead to content-negotiatable representations in HTML, MARCXML, MADS, RDF, etc.
