We’ve done this in every game since we started playing Global; we just thought it made sense. West India goes to the Pacific side, while British Columbia/Yukon go to the Europe side. This results in a simple +1 Pacific UK / -1 Europe UK IPC switch. However, any Middle Eastern neutrals later captured get administered from London, of course. Your point, however, on second thought, about the minor IC in West India may actually be what the designer(s) had in mind when they chose it. I don’t know myself. We’re still going to play with this house rule until they just make official.
