Merging two custom builds of uBlue. Is it possible?

I was thinking about say… Bazzite + Secure Blue. Would it be possible to sort of ‘‘fuse’’ them together without having to start from scratch?

How could that be achieved and how difficult it would be?

As a side note, it feels like the future. Mixing opinionated, niche builds into a more holistic versions. I could see big potential of individualization of use cases like say… one uses X + Y combination, whereas other uses A + B + C combination etc.

Then there could be a more general but still somewhat opinionated builds combining few smaller ones. Then maybe there even would be a huge one containing dozen of unique and complementing builds.
