That will end in about half the time as DE. Sometimes even faster than that. If people demand at least two matches, have a consolation tourney for the first round losers, if there are plenty of tables.
With SE, you could add a game or two to the match length and still finish much earlier.
In my area a Monday night tournament is run as a modified double elimination. Bar box. Usually eight ball on the A side and nine ball on the B side.
Once you get put on the B side, there is no coming back to the A side. The B side plays as normal but 3/4 doesn’t play - they split the B side pot. The A side can split the main pot if they want or play it out (the A side almost always finishes first). Handicap races.
Same pool hall also does a 9’ 9b tournament with a similar format. B side never comes back. Race to 4 on the A and 3 on the B (handicap entry).
Both tournaments are popular.
