If Zeon wins the OYW, let alone by getting the Gundam and Amuro and the White Base never being threats to them, why would Zeon not already have the resources to do so before 0085? Zeon is also increasingly defined by reckless acts fueled by propaganda, and winning the OYW would supercharge that. The Guncannon Light would be a poor replacement for the Gundam and the GMs, and MSG 0079 showed that Sayla is not a good mobile suit pilot and takes ages to get decent, and that's when sharing the same ship with Amuro.

If Char and Chalia decimated the Federation fleet at Solomon, wouldn't that just support the idea that Zeon had less losses than in 0079 and the Federation had more? Why haven't the Big Zams taken over in the years between the Zeknova and GQuacks? Why haven't they amassed whatever resources would be needed for the Solar Ray?

The show doesn't convey how that would feasibly be the case though. MSG 0079 makes it clear that Amuro and the White Base crew play an instrumental role in the war and helping the Federation win, and GQuacks starts with Amuro and the White Base crew being non-factors and Zeon getting both the Gundam and the White Base's sister ship. Until Episodes 1 and 2 of MSG 0079, the war is in Zeon's favor.
