I think both of these will prove very useful in certain circumstances, ie good way to add a bit of temporary space and delay any thoughts of swarming before the contents get transferred to a full size box.

I'm more of the opinion that it would be more efficient to move them into a full sized box than adding height to a narrow unit, making it unstable, also having another lot of equipment just for nuc expansion when a six frame nuc when full is ready to explode into full size equipment already in stock with no need for specialist queen excluders or supers.
I have met beekeepers who use 8 frame equipment exclusively mind, and they seemed to do quite well, if a little labour intensive to hold them from swarming.
