Running on tmpfs (like profile sync daemon) - possible?

So, I am a fan of PSD ( Profile Sync Daemon ), which reduces writes to disk and thus speeds up the webbrowser. It works by copying your browser profile to tmpfs (in RAM) and then you basically run/use your browser profile from memory. It also does a regular sync, to create backups.

Since I’m using more and more snaps with every passing month, I was wondering if something like that is also possible with snaps? Because I can also imagine that creating something like PSD, would interfere with the sandboxing tech of snaps. So before trying to create something like this, I thought I’d ask around if it would even be feasible. Wonder what you all think about this?
