Not really. For starters, no schedule is ever published with a GS in it.

Let's say our category pays $100/hour. Say the ALV is 83. Using 1.5>80, PBS might build me a line at 90 hours where I get paid $9,500, or an average of $105.56/hour, and you might get a line of 80 hours, paid $100/hour on average. You might be senior, but that's just the way the cookie crumbles under PBS.

So right there, the 1.5>80 system has penalized a pilot on an arbitrary basis, disregarding seniority. It's built in.

The GS system, which the 1.5>80 would either replace contractually, or make irrelevant in practice, creates no such inequity, because the flying is not routine. But, in a tight staffing situation, it does come into play, and it then rewards pilots for helping the company's problem. In doing so, it changes the average rate of that pilot, bit it does it 1) by respecting seniority, and 2) by ensuring a distribution of GS throughout the list, before the senior pilot gets a second helping.

1.5>80, OTOH, does not have the second provision listed above, AND it can be bypassed by the loophole of SB/SWF, which confers the right to a senior pilot to pick-up then distribute flying as he sees fit, disregarding any WS pick-up limit. The pilot immediately junior to him would not be able to pick-up the trip, and depending on his social connections, would not get the flying before a junior guy that swapped with the senior-most of the three.

So no, you can't really make the same arguments about the GS system. The GS system comes with protections, but 1.5>80 is a free-for-all, where PBS and other pilots determine who gets a raise, and who doesn't.
