Not quite. We acquired the long thought lost PC source code for Saints Row 2, and are working on fixing the PC Steam version of the game. This has nothing to do with any other platforms.
While we created the original game back in 2014, we were not involved with the Switch port. Your best bet would be to contact Deep Silver support on this:

We can't comment on the possibility, other than to say it wouldn't ever be from us. Our focus is on creating new content. Ports of our older games are handled by other studios.
