If you can 100% guarantee to kill all the bad guys pre-merge, you only need enough g to position to shot them and turn round once they're all dead. If out-numbered, targeting isn't perfect or Pk/counterneasures leave survivors of the first fox-3s then you have a choice. Blow-through, run and at sometime come back to re-engage. Turn and run, neatly placing the bad guys behind you or stay and fight. Even with off-boresite weapons and versatile aiming, turning at 7g against a 9g+ opponent is a massive disadvantage and is likely to end in tears.
F-15 and F-22 air-to-air pilots are trained to fight at maximum g at corner velocity. Any less and you lose.
Even LM can't change all the laws of physics.
Just This Once... indeed. Take those bulky red things out and there'd be space for more real weapons.
