Yes. Just add 500 other candidates, and fill in the gaps with
randomly-selected candidates from the 500. Obviously, you could probably
get by with a lot less than 500 — at a rough guess, I'd expect that 8 would
be plenty without changing the numbers here, and probably around 4-6 would
be enough to make a similar example with smaller gaps work, but my point is
that with enough extra candidates who cluster at the bottom of most
ballots, you can turn any rated scenario into a ranked scenario.

You are being tempted by a mirage here. The first lesson of "voting school
kindergarten" is that most problems don't have a perfect solution. That
doesn't mean you stop looking for ways to improve things, but it does mean
that when you imagine a "fix", you do your best to shoot holes in your own
idea. 95% of the time you'll succeed, but the other 5% still makes it worth
it.
