The coupling of the motions within and below te photosphere to the chromosphere and corona is one of the fundamental issues in solar physics. We have developed a model coupling the simulated dynamics of sunspots to the simulated heating of coronal loops. In this paper we present an extension of our earlier work to the inclusion of (a) fully three dimensional magnetoconvection, (b) new analytical representations of hydrostatic loops with spatially-dependent heating rates and (c) fully time-dependent hydrodynamic coronal modeling. The dynamic loop model uses the same numerical scheme as the magnetoconvective model used to simulate the photospheric behavior in this sunspot system, making it possible to more fully integrate the two regimes. We present the first results of a hybrid model utilizing a time-dependent coronal model and a fully three-dimensional magnetoconvective model.
