No, you cannot.

You can override Application.ShowException, but then you do not know the
current request.

What I do is make a descendent of TFPWebModule which overrides
"HandleRequest', and which handles exceptions in a generic way.
It returns JSON when the request expects JSON etc.

All my other modules are descendent of this descendent.
