Yes, it can be done.
I only have two features ("Hub" and "Edge") that are exclusive so my example is
a bit
simplistic compared to something with more exclusive features, but you'll get
the idea.
I created a custom error dialog, "MG_FeatureError", that says;
"One, and only one, of the sub-features may be selected."
Then in the UI section of the project I have this;
<UI>
[snip]
<!-- If multiple NewDialog and SpawnDialog control events are selected for
the same control, -->
<!-- only the event with the largest value in the Ordering column gets
published -->
<!-- when the control is activated. -->
<!-- http://msdn2.microsoft.com/en-us/library/aa368037(VS.85).aspx -->
<Publish Dialog="CustomizeDlg" Control="Next" Event="NewDialog"
Value="MG_FeatureError"
Order="3"><![CDATA[&Hub=3 AND &Edge=3]]></Publish>
[snip]
Your conditions will likely get large/messy, but it can be done.
( &FeatA=3 AND (&FeatB=3 OR &FeatC=3 OR &FeatD=3) ) OR ( etc... )
This does not enforce the restriction on installs with no UI, but hopefully
the people invoking from the command line read the documentation...
