The way I've ruled this is that you are adding the crit before the modify dice step and that is why you cannot use target sync. My ruling is in the same vein as Zuckuss rerolls C-3PO's added result.
You are wrong about this. C-3PO specifies a trigger point outside the modify dice step, which is why he works when he does, as does HLC. They're exceptions, not the rule. Unless specified, all modifications to attack and defence dice take place in their relevant steps.
