My first reaction to this was "No", as I think one of the problems with Traveller's growth is the frequent tight integration with the OTU and it's wealth of data. But it sounds like what you're actually proposing is a switch to the "core-rules-and-seperate-worldbooks" model, which would achieve the kind of seperation I think is needed while consolidating the OTU background material. IMHO, that's actually a good idea and long overdue.
