Hmm, yeah, you're right --- at least one of the first two words needs
to be reserved (not something that can be a ColId, at least), or else
we can't tell them from a table name and alias. So this approach
doesn't give us all that much extra wiggle room. We do have a number
of already-fully-reserved prepositions (FOR, FROM, IN, ON, TO) but none
of them seem like great choices.

Meh. I don't find that analogy compelling.
After sleeping on it, your other suggestion of TABLE OF, or possibly
TABLE FROM, is starting to grow on me.
Who else has an opinion?
