I have tried some MF and LF lenses with my Leica R-Sony Nex Metabones SB. It doesn't matter that the lenses have a huge image circle - the SB will only cover APS-C.

False. Most designed-for-APS-C focal reducers will cover a 24mm square, and perhaps a bit more... which is useful.

Precise measurements are difficult to make but the circle they iluminate is slightly larger than their covering circle without being really useful. However, what's important in this discussion is that they don't cover FF.

I know you're disappointed, but just because it doesn't fulfill your dreams doesn't mean it isn't useful. The ability to take a FF lens and get a square aspect image with the same view angle as full frame is really useful -- if you like square images.

I am aware of how difficult should be to make a 0.5 FF SB. My intention is only to make an useful tool for me in order to enjoy the "character" of some of my older LF lenses on a digital camera in situations when the corner sharpness is not so important - that's all .

Well, that will take a larger-format focal reducer. However, being able to get a square image out of your FF lenses with the same field of view sure makes them feel a lot more 6x6-ish to me.  YMMV.
