Yes, you could do that. However, this leads to a great incentive to rank
the candidate you preferred second, with some nonsense candidate in
first place. The can't-win candidate shields you from being
downweighted. For instance:
DQ/2 + 1: X1 > A > B > C > ...
DQ/2 + 1: X2 > A > B > C > ...
(...)
If A, B, or C wins, then these two blocks (a Droop quota plus two worth)
contributed to the winning candidate's victory, yet they're not
downweighted.
