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).
