I doubt that you can beat the Bayesian approach if computational cost is 
not a barrier. Essentially you need to be able to compute the observed 
data from the high resolution model image, and also the matrix transpose 
of this operation. Armed with these two transforms you can use various 
maximum entropy or other constrained non-linear least square methods to 
find a model image consistent with the observed data to within the noise.

I suspect that you will not get much more than a slight bleeding of the 
high resolution data decaying exponentially away from edges of the high 
res areas (with a rate depending on the half width of the effective psf).
