Sure, as long as you don’t need any integration with other software, don’t need arbitrary IPC, and actually keep some dependencies in line with some common denominator because there’s only so much you can do with static linking (oh excuse me, distributing the shared libraries in the same package as your binaries as if it’s a new thing) once it reach the “program must actually run” part.
Flatpack and every other similar solution that are described as “works everywhere” always come with a heck of limitations.

Thunderbird, MegaSync, Bitwarden all distribute as flatpak just fine, and it covers most of the functionality of proton suite.
Ironically the only two services this list doesn’t cover, Proton VPN and Proton Bridge, are on flathub…
Last in checked email ain’t all that complex, so seems like a good match
