It's entirely possible. I'm working on getting the Android sources for Cosmo so I can link my new WIP CoDi daemon into it, improving flashing too, but I don't know if PC will allow me to have the sources. Gemini.. I'm waiting for some libraries to be updated, but it IS possible to get current Lineage on it. Astro, I hope to get a pre-prod unit of that and Gemini to get Lineage on. I have a spare Cosmo which I do for Android and CoDi dev.
Planet will most likely ask the community for help with ROMs, as before, but I'd really like to get automated Lineage builds on Gemini, Cosmo, and Astro.

With regards to Planet - they're very busy right now, and I haven't heard anything from PC with regards to CoDi/pmOS/LineageOS, which I *was* focusing on, but have since put to the side while I work on my hybrid KVM switch.
I now have a build server donated, and there's Telegram groups I run for the above projects. Planet are unlikely to ship custom ROMs by themselves.
Let's put it this way - don't get too excited just yet. I'm currently waiting to hear back from some other companies for jobs, and even then, my work might need to be put on the backburner, should my employment obligations conflict.
