Classic Drax (w/powergem)/Surfer/Thor/Stardust vs Jla

Everyone on each side is out for the kill and theyre using all of there abilities to the fullest.

Jla consist of:

Superman
Wonder woman
Martian manhunter (no tp)
Orion (no mother box)
Green lantern (hal)

Can the jla take out the opposing team?

doesn't the power gem make you invulnerable? and someone said that it can shield you from the living tribunal.
