Happy New Year to you too.
Concerning the question how to connect regions B, C, D with sub-regions A1, A2, A3 & A4, I think it would depend on how you model these sub-regions in (there is no concept of sub-region implemented in the TIMES model generator itself). If you model them as regular regions, I would think that you would need trade processes between A1, A2, A3 and A4, and I think I would also connect B, C, D directly to these A* regions according to the physical proximity, as you put it. But sure, you could also keep a "master region" A for the original full region A, and let all trade involving A go through that. Alternatively, you could also model the sub-regions without introducing new regions for them, by introducing sub-regional processes and commodities.
I am thus not able to give any recommendation, but I think it is up to the modeller to decide which is the best approach for his/her model. But maybe some TIMES users who have more experience with sub-regional modelling might be able to give their suggestions.
