Hypothetically if the House size were increased, would make gerrymandering better or worse?

I've been thinking about this a lot lately and it seems like a case can be made either way.

The case that it would help to make gerrymandering better is that by adding more seats to a state, you have to generally cede a greater proportion of seats to the minority party. This is because larger seats are able to span across the state and take in very unique and different communities far apart whereas there is a more physical limit as to how far smaller seats can stretch. In nearly all cases with the exception of a few close states with extreme geography, the minority party won a greater share of state legislative districts in the lower House on 2020 Pres numbers than the share of CDs won. This isn't because the congressional maps are necessarily any more or less gerrymandered, it's just as you add more seats it becomes impossible to deny certain communities' representation. It also makes it harder to absolutely eliminate all swing seats (except maybe in teh South where geography makes that hard anyways)

On the flip side, it would allow parties to gerrymander in states that right now can't be gerrymandered from a partisan standpoint, either because they only have 1 seat, or are so one sided that drawing a seat for the minority party is impossible (think WV) or there's just very few options as to what you can do. Also, states like MS where VRA creates a pretty inevitable 3-1 map could become greater redistricting weapons.

Either way this is just a hypothetical unlikely to happen but an interesting thought
