Is there any hope of getting these operating systems (grapheneos/leaniageos) to run on anything other than the pixel phone?

I've been using Samsung all my life (tablets, phones, watches, TVs) since they've been providing consistent quality, but after samsungs silently leaking my keyboard input to grammarly and not providing me the features I paid for on their galexy watch, I decided to move out of the samsung echosystem for good.

The thing is that I still really like their hardware. I just want to change the software running on it to something more sane and less shady.
