If by mixed GWR you mean a model where some of the coefficients are held fixed at the global level, and others vary locally, this is equivalent to fitting a global model first and fitting the local model to the residuals, but watch out for the intercept! This omits the possible covariance between the global and local subsets, treating the global as a known offset, so if you like, you can do steps 1-5 of pp. 67-8 in the GWR book by hand and see if there is a big difference. In any case, GWR is not an explanatory model, as I expect you are aware.
