Doesn't this do what you want?

        linux32 emerge -avt mozilla-firefox

>From the manpage for linux32:

        linux32  creates  a  32bit  environment for the specified program, usually a shell.
        The environment is inherited by all child processes of that  program,  unless  they
        set  a  different  personality.  The 32bit environment currently means all uname(1) 
        system calls (and thus also the outputs of the  uname(1)  program  with  -m  or  -a
        options) will return a 32bit type instead of a 64bit type as the machine type.
        
        linux64 can be used to temporarily switch back.
