a couple of ideas for legislative bodies, what are some far-out ideas for how to organize and purpose them?

it would need to actually represent the population while being capable of producing effective legislation. a couple of ideas:

different levels of legislature, regional bodies where the reps are elected via instant runoff voting. then each regional legislature can elect one rep for a federal senate. then that senate can be balanced out by a house of reps, elected nationally, via instant runoff voting ignoring any regional lines. These two national bodies can balance each other by requiring that the other pass the same piece of legislation before it becomes law.

two legislative bodies elected via the same method except one is dedicated to writing new laws while the other is dedicated to repealing laws. this way the legal code could be streamlined and constantly updated to keep with modern times.
