This might be off topic, but in case its of interest,
why should C not given both wins/seats/voting power units?

If its because we must fill two litteral seats and
(possibly quite sensibly) refuse to use party lists
then we could just use something like "reserved seat numbers"
where representatives gains voting power units equal to
the number of seats they reserved in the election.

Depending on ones priorities, some people will find such an
implementation an improvement because the elected candidates
can then be directly held accountable for their votes,
rather then today where party mebers are simply doing their job
obeying the party line.
The individuals will also have more barganing power against lobbyists
increasing the expected cost of lobbying,
at the possible risk of slightly makeing the process easier to get in on
(good if you believe in competition, bad if you don't for this case).
