I don't think you have done an excessive amount of consolidation by the sound of it. Bodmin isn't the easiest of airports, especially in the winter. It probably would be reasonable to go somewhere with better weather for a couple of weeks, treat it as a holiday with flying, do some navs solo and dual. No need to go to the USA, if you stay in Europe there are plenty of places with decent weather and English speaking instructors available. Then back home to finish off.
Aim for about fifteen hours, enough that you get the benefit of your trip, including possibly getting used to a new type, but not so much that you are panting to do the skills test.
Remember, it's supposed to be fun.
