Here are my proposals:

The Senate is elected similar to a parliament from other countries. Country-wide votes for parties, with proportional representation. It would balance out the regionality of the House.

The Supreme Court justices serve terms of 12-16 years. Each presidential candidate must select 2 supreme court picks at least 4 weeks before the election, and whoever wins has their picks placed on the court. (After their term, supreme court justices retire to the DC circuit).
