I, too, was puzzled by the intersection of 8 Down and 14 Across, so I asked a knowledgeable friend and learned that the troublesome feature of the shared letter is often dropped in upper case. Though in any case I hope any reasonable presentation will be accepted.
The across words intersecting 8 Down don't all change in the same way when the instruction is applied. In some, the sound is permitted to change so that the spelling can remain the same (so to speak), while in others, the spelling is permitted to change so that the sound can remain the same. There's no ambiguity about the intended answer, but the lack of consistency seems like maybe a small flaw in execution.
Nevertheless, I was tickled at how neatly everything came out. Lovely piece of construction!
