Sam,
Chaining installers is a general no-no and Microsoft recommend you don't
do it. Second, trying to install software in the Cost Finalise stage is
also not a good idea. Installing something using a custom action makes
it very difficult to roll back should the installation fail or be
cancelled and it makes uninstalling your application difficult if not
impossible. Your installer should allow a clean install and also a
clean removal of you application (including DirectX if your applicaiton
installs it) and given the design you are describing, that would be
difficult to achieve.
If you need to install a second application, the recommended method is
to use a bootstrapper such as dotNetInstaller or WiX's own "Burn"
facility. Its likely to cause you a lot less headaches in the long run.
