The closest you can get probably is grok.traversable:
http://grok.zope.org/doc/current/reference/directives.html#grok.traversable
but than will need you to have methods which are defined on your Model
class instead of on your view.

You can than add an adapter for string-like objects, which returns the
things as-is, like

class MyStringViewer(grok.View)
    grok.context(basestring)

    def render(self):
        return self.context

[*] completely untested code here, but it might work.

Cheers,
Jasper
