Recently, U.Bunke and others developed in a number of papers (such as this, this or this) an approach to smooth extensions of cohomology theories based on stable homotopy theory. In this approach a differentiable refinement of a cohomology theory is a sheaf from the category of smooth manifolds $\mathbf{Mfd}$ to the category of spectra. Of course proving that in this way one gets a cohomology theory satisfying an analogue of the Eileneberg-Steenrod axioms.
My naive question is the following: can one make a similar construction for the category of complex manifolds (with holomorphic maps) and obtain some kind of analytic refinement of cohomology theories?
