It probably is possible from a technical point of view but I dare say the the Home Office would take a dim view of it, which is why the upper and lowers are built so as not to be compatible with a standard AR.
Also, incompatibility (i.e. non standard uppers and lowers) allows SGC justify the price, IMO.
You are spot on. None of the locating pins and coresponding holes on the SGC lever release uppers and lowers align with the ones on standard AR15 upper and lowers. This prevents, what is in effect, a semi auto upper being mated with a lower which will enable true semi auto functionality.
The fire control group pins and holes in the SGC lever release lower are also non standard to prevent the insertion of a standard ar trigger group which, again, would enable semi auto functionality. As much as I don't like Bob he has built in a number of safeguards to ensure his lever release ARs could not be considered readily convertible to section five.
If you take a straight pull AR and attempt to build in lever release functionality how could you ensure it would not be readily convertible to section five, given the locating pins and holes would all be of a standard AR configuration? Weld the upper and lower together possibly? Not sure how else you could come close to delivering the safeguards Bob has built in to his version.
