How does the Starfinder 2e soldier fare in Pathfinder 2e skirmish combat?

To nobody's surprise, bringing the Pathfinder 2e skirmish rules over to Starfinder 2e results in a bloodbath for troops, because Starfinder 2e has Area Fire, Auto-Fire, grenades, and grenade launchers. Besides, it would be fairly weird for futuristic military personnel to willingly bunch up into squares.

What about something more subdued, though: bringing a Starfinder 2e soldier over to Pathfinder 2e, using archaic, melee reach weapons? Think Dynasty Warriors: carving into ranks of troops with area attacks. Does a soldier prove overly powerful in such a scenario?

I think it might not be too bad, particularly since the attack penalty from the suppressed condition would not actually apply to troops, who force Reflex saves instead of making attack rolls.
