Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:   present a discrete Fourier transform based procedure to evaluate the infinite domain solution of Poisson's equation at points in a rectangular computational region. The numerical procedure is a modification of an "expanding domain" type method where one obtains approximations of increasing accuracy by expanding the computational domain. The modification presented here is one that leads to approximations that converge with high order rates of convergence with respect to domain size. Spectrally accurate approximations are used to approximate differential operators and so the method possesses very high rates of convergence with respect to mesh size as ll. Computational results on both two and three dimensional test problems are presented that demonstrate the accuracy and computational efficiency of the procedure.
