Slurs, ties etc from outside to the second voice would still be
forbidden.  The problem really is that Lilypond's notion of continuity
(we have that also in repeat alternatives, codas and similar) is too
naive.

The above would not solve it.  Some things would work, some things would
not.  Depending on the voice they happen in.

So don't get your expectations too high about what gains can be expected
from implementing that proposal.
