I don't know if Debian would be willing to make official packages with relocatable installations (ie, /opt-style installation aka application bundle) but that would help solve the problem (up to conflicting external dependencies, but I doubt Emacs has many "must equal x.YY" dependencies). I don't do it any more (running in-place is easier) but I did experiment with it successfully a while back for locally created dpkgs of XEmacs. The idea is basically that you can have a complete set of {bin,etc,lib,man,share} trees under /opt/local/emacs-x.yy (ie, the arch-dependent files would end up in /opt/local/emacs-x.yy/lib/emacs-x.yy/x86_64-pc-gnu-linux/ or similar), which is pretty redundant, but means that the versions don't compete for the same file names in arch-independent hierarchies. For more information about how this is managed, ask Mike Sperber about --with-prefix=no. I don't know the details.
