This is done in some places in Zope, for example where a layer (being
an Interface really) is registered as a skin by making this interface
*provide* IBrowserSkinType. Grok does that here for example::

 http://svn.zope.org/grokcore.view/trunk/src/grokcore/view/meta/skin.py

In other words, I do not know of a way other than via provideInterface.
