I see from your response to the Electowiki  "Method support poll"  that 
you "nearly  support" the ER-Bucklin(whole)  single-winner method,
and  that for  "Legislative election methods" you like "possibly a 
proportional approval scheme".

What do you think of  this PR version of  ER-Bucklin(whole) ?

"Voters rank  candidates, truncatation and equal-ranking ok.
The winning threshold  to elect the first winner is a Droop quota 
(number of valid ballots/number of seats +1).
(1) Commence the ER-Bucklin(whole) process until the candidate with the 
highest score has a winning threshold.
Declare that single candidate elected.
(2) Reduce the weight of all the ballots that contributed to the 
winner's tally by an equal amount which sums to a Droop quota.
(3) Based on these reweighted ballots, the reduced number of unfilled 
seats, and not counting as valid any now exhausted ballots,
reset the  Droop quota.
(4) Repeat  the above three steps until all the seats are filled."
