If you go the 14 x 12 route - and I am not suggesting you should, at least at this stage - getting them in from a National deep frame is an absolute doddle. Just fill the space under the deeps and they will expand onto the larger format. Need to work at it, yes, but easy.
Changing to 14 x 12 from deeps is simply a matter of fitting an eke under the brood and changing them into it. Home made eke is about four quid and a new set of frames ten quid plus the foundation.
