On current Fedora, you can install 32 and 64 bit versions happyly (most of the time), the installed packages do share non-architectured stuff (like manpages and whatnot). Yes, it does require some delicate juggling when building the packages to make sure said manpages and such are exactly equal and some other considerations.
