I did this in my own home. I pulled the toilet, replaced some of the subfloor, cleaned off the tiles and reused them, but I wouldn't try it if it wasn't mine.
A repair like this is seldom as easy as it seems, and it's always a "never-really-know-what-you're-getting-into-until-you-tear-it-apart" situation.
They often snowball into something bigger than you bargained for.
Edited to add: Oops, slow typist.
