Supposedly also, there was at least one working prototype 1016 made, which would not been hard to do given an existing large-frame platform (4516).

In case anyone wants to jump on the idea of making their own 1016 I played with that thought in my initial workings on converting my 4013 to a 1013 & passed on it.
The 4013 & 4516, while both large frame compacts, are not identical, not surprisingly.
Naturally 4516 magazines have wider lip openings than 4013 mags but the magwells are, unfortunately, slightly different sizes in these two models. S&W fixed that oversight when they made the 3" barrelled CS40 & CS45 sub-compacts, some years later, which have magwells of the same dimensions & provides a basis for interchangeability.
The 4013 & 4516 frames have dust shields of different lengths. (The 4516 has a 3-3/4" bbl while the 4013 is 3-1/2" long)
Their ejectors are of different length.
The position at which their respective slides lock back on their frames have different relationships to each other, which is more of a problem in the .40 to 10mm conversion.
Of course none of this would have been a problem the factory couldn't have resolved in finalizing a functional M1016. It's just harder after the fact.
I documented the above findings, & conversion process to 1013, in my picture laden thread here on the forum:
