Is 2-oxobicyclo[2.2.1]heptan-1-ide resonance stabilized? Is the following compound resonance stabilized? 



I think its not resonance stabilized because the p-orbital of carbanion and pure p-orbital of carbonyl carbon are not in same plane. So they can't overlap. (Pure means that the p-orbital is not a part of the $\ce{sp^2}$ orbital. One p-orbital of carbonyl carbon is pure).
Am I correct?
I think, in contrast to cyclohexanone, a resonance stabilization by 



is less likely to happen as you already start with a bi-cyclic compound where the cycles involved are small to moderate. The then additional strain introduced by a (partial) double bond at the bridge-head carbon atom would destabilize the molecule too much.  I extrapolate here from Bredt's rule.
