How about this for teams 5-12. To give the 5 & 6 seeds some love and to limit overall travel time and expense they would both play host to 3 other teams and 3 games total over 2 days. (Monday & Tuesday)
(5)-12, 8-9, then the winners matchup. Overall winner travels on to Cleveland on Wednesday to either play 3 or 4 Thursday depending on reseeding.
(6)-11, 7-10, then the winners matchup. Overall winner travels on to Cleveland on Wednesday to either play 3 or 4 Thursday depending on reseeding.
