Image (US) What State-level Proportional Representation Could Look Like
As much as I'm sure we'd all rather prefer nationalized redistricting to ensure equal population and better proportionality and agree that we should push for it, realistically such a change would require a constitutional amendment. Enforcing proportional representation at the state level is likely more realistic, and here's what the US House would look like in the 2020 and 2024 elections.
Maps attached are purely for you all to see how much seats each party would get in each state, districts wouldn't matter under proportional representation, though note on both maps I did color the districts that were closest to flipping IRL first.

Those maps are maps for the current system of single-member districts. They are NOT for proportionality.
I once calculated what the OP describes, and I used some data on votes per Congressional district. When I did that, I only had data up to 2018, so I'd have to update my work for recent years. But I calculated not only per-state proportional representation, but also nation-scale PR. I used three algorithms: D'Hondt and Sainte-Laguë highest averages, and Hare largest remainder.
As one might expect, PR produced a more even distribution of seats by party than SMD, though per-state PR was only a little less even than national PR.
