Turn each state into a multi-member district. Small states with only one rep can be combined with other states to form three-rep blocks, i.e., North Dakota, South Dakota, and Montana can be combined into one election. Elections can be party-list elections. For example, Utah has 3 seats; each party puts forward a list of 3 candidates, and the voters vote for the party of their choice. There's no longer a need to redraw lines because there are no more lines.
