Jobst,
how about this slight variation on your suggestion?
1. Ranked ballots with truncation.
2. Draw a ballot at random.
3. Draw additional ballots at random until there is one that has at least one
ranked candidate in common with the first ballot, or until all ballots are
exhausted.
I like RPR. The additional control that this gives to voters might make voters
less squimish about proxy.

I like the idea of giving candidates the option of withdrawal before each
potential elimination.
It seems true that most candidates would be more reluctant to withdraw than
their supporters might want, but if no candidate withdraws, then IRV with
withdrawal reduces to plain IRV, no harm
