A MILLION TIMES YES

No but like the angst potential?

It's after Weirdmageddon, Bill is gone, Dipper and Mabel are back in Piedmont and Stan and Ford are sailing on the StanO'War.

Ford didn't get around to tinkering with his old projects until then, worrying about too many things around Bill and then Stan regaining his memory. However, finally, he has the time to look back.

Finding the googles all fixed up and fully working (all by accident, mind you) opened up so much potential for more discoveries.

He could look back and study the details he's previously missed or didn't pay as much time as he wanted to. He is ecstatic to have such an opportunity, all thanks to Stan.

After some time, he starts wondering about things other than research. His life, mostly. His and Stanley's. How many things have they already forgotten and could now see as if they happened the day before? It'd also help with Stan's recovery and fasten the process.

Once, late into the night, he finally decides to sit down and look back at their lives. He finds hidden details, relives the happiest moments of his life as well as the hardest. He can't say he's been the happiest throughout his life but it's been good.

Then he looks at Stanley and something breaks.

He sees their childhood from a completely different perceptive. He isn't the smart twin anymore, he is Stan. The one that was always considered less, the one that was offered for just a few bucks by his own father, the one that stood up for Ford and was there through thick and thin.

And they get older and the guilt in his chest gets heavy with every screening.

The hidden, unfulfilled dreams and ambitions, the hardships and hopes for a better future on StanO'War. All for it all to come crumbling down because of the science project which, in the end, wasn't actually Stan's fault at all. Ford finally realises it, over 40 years later.

He can't take his eyes off of the googles even despite the pain he feels from seeing Stan be kicked out. He watches his own brother be thrown around and used by people, life forcing him on his knees, as if punishing him for simply existing. The breakdowns, pain, nearly deaths, it all shakes Ford to his core.

And he feels awful when he watches himself disappear into the portal only for Stan, the brother Ford left behind for success, to take it upon himself to get Ford back. Stan spends 30 years studying subjects he doesn't understand and trying to fix a portal with a single journal, all to return his twin brother home.

The first thing Ford does? A punch to the face. And Ford can feel the punch as well, the reality being thrown at him with such overwhelming force.

Stan doesn't understand why Ford doesn't touch the googles again and becomes so much more understanding and appreciative towards him.

Sorry if it sounds like rambling, it's like 1 AM and my mind is all over the place to be honest.

Stanford Pines had been working in something amazing before he encountered Bill. It looked like a tape but it would be used to have a look at different times without interacting with them, he had a whole plan for it: Goggles, some sort of virtual reality goggles that would let you peek into the future or past without worrying about altering anything, and the tape to select the time period you'd like to watch.

It is, unfortunately, no where near complete. His muse has told him to focus on something greater: the portal.

Stanley Pines had messed up, shocker. He broke one of his brother's projects again, a measuring tape looking machine.

On nights he doesn't know how to fix the portal, he sounds ficing that tiny machine. The design is lame but he tries to keep it true to it's original form and, despite it breaking because he was an idiot, he feels accomplished when he finishes it and puts it back in it's original place.

30 years later, Stanford Pines returns only to find out his brother had accidentally created the very first time tape.

(Or: Stan fixes the time tape/watcher a bit TOO well and becomes the founder of time machines basically)
