First, this is an issue to be discussed within the LSB community,
not in the Fedora community.

Some more comments (assuming in (2) you meant /usr/bin32):

-  As you point out yourself, apps expect to look in /usr/bin.
   So both suggestions cause problems to find apps that are only
   available in 32-bit format, which is a serious problem.

-  In case (2), 32-bit packages would have to be built twice: one
   time for 32-bit systems and one time for 64-bit systems.

-  The issue with 32-bit apps is in a lot of cases to support
   third party 32-bit software software on 64-bit systems.
   Option (1) conflicts with with this and it is important to
   realize that third party vendors will in most cases not
   provide two versions of 32-bit packages.
