Using MSI Automation object "WindowsInstaller.Installer", we can query data about installed products but, is it possible to modify these cached values?

You can do a few things, like installing a feature that is now installed-on-demand, repairing a component, and change the installation state of the whole package.
Note: I've done stuff like this, using the Windows Installer API (like MsiProvideComponentPath etc.) I'm not sure that the Automation interface has similar methods.

Note that you can't change directories, properties etc.

To change the installed product in any fashion, use a (minor upgrade) patch.
