Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Sparse Gaussian graphical models characterize sparse dependence relationships beten random variables in a network. To estimate multiple related Gaussian graphical models on the same set of variables,  formulate a hierarchical model, which leads to an optimization problem with a nonconvex log-shift penalty function.  show that under mild conditions the optimization problem is convex despite the inclusion of a nonconvex penalty, and derive an efficient optimization algorithm. Experiments on both synthetic and real data show that the proposed method is able to achieve good selection and estimation performance simultaneously, because the nonconvexity of the log-shift penalty allows for ak signals to be thresholded to zero without excessive shrinkage on the strong signals.
