In your installer, you should have it create the registry settings for the snap-in instead of calling InstallUtil. Wix 2.0 has a schema extension to do this. Then, you put the MMC in its own component that is shared by both products. The Windows Installer will automatically do reference counting on the component and will only install it when it doesn't exist and will remove it when no more products are installed that use it.
