This is an interesting concept. Put the vote multiplier on the backside instead of the front. The Wyoming rep gets 1 vote, but the California rep gets 1.8, etc. This would allow for smaller bodies for more effective debate and you’d give smaller population territories over-representative expression in those debates, but you’d tie the outcomes to be proportional to the populations each representative represents.

I think this is a clever way to keep a cap on a parliamentary body’s size while allowing for more egalitarian representation.

Wouldn’t help combat the other problems of a capped body size (worsening gerrymandering, for example), but it’d be a step in the right direction.
