Triple Boot Installers? (XP/VISTA/7)

Hey guys, new to the forum.

Been looking around the forum, and I know that it's possible to leverage BCD to triple boot installed OS's, but is it possible to use it to make a triple-installer drive? What I mean is, have 3 partitions, each containing the installer for windows xp, vista, and 7? So it'd look like this:

C: - XP Installer
D: - Vista Installer
E: - Windows 7 Installer

Any suggestions? I've been trying this unsuccessfully in a number of different ways. Thanks!
