Decomposing a distribution into Gaussians is the essence of unblurring. A good algorithm for doing that would of course be very useful, but there is an enormous literature on the topic, and the most important fact about it is that it is mathematically ill-posed. In other words, unless you add extra constraints, tiny changes in the source distribution result in very large changes in the output. (In image-processing terms, transforms of that type tend to create large artifacts.) Unless the new method has some way of handling that problem, it probably isn't going to be useful.
