Gestalt Precision Damage Stacking

[CGNefarious]

So I'm currently in a Gestalt We Be Goblins campaign and the idea of a Rogue//Stalker (from Dreamscarred Press) came up. My question is if sneak attack and deadly strikes would stack if said character were to crit on a flanked victim?

Probably they have different names also throw in some scout levels and use the multi-classing feat for scout/rogue.(still another name allowing you to stack even more precision damage)
