How Can I... Regain lost resolution (lemmy.one)

Some of the photos I take, to get the subject large enough in the frame I have to use electronic zoom. I don't have money for a nice zoom lens. I tried using an adapter for one of Dad's zoom lenses but it sometimes gives me issues. So I use a 4x zoom - which basically cuts off 3/4 of my sensor then expands the picture to full size (I guess by some sort of averaging math to create the discarded pixels)

Is there anything I can do in post to get some of that resolution back - even if it made up. I am a Linux user, so a workflow in GIMP would be great, or any other Free/Libre software you might suggest?

An example: along Highway 20 going west from Williams - one may see a single mountain in the coastal range that has snow. I took several pictures starting near Williams, but as we were just starting to get close enough, the closer mountains started to block the objective mountain.

So I have some pictures with a tiny mountain, and some when I used the e-zoom and have a more frame-filling mountain, but at a lower resolution.

And Yes, I am aware that CSI-Enhance is a fantasy used to uncover evidence in a tv show. AI-hallucinated pixels are fine with me for this, as long as the hallucinated pixels look plausible, and are not entirely made up details.
