Can't quite get there. I think that the three unclued pairs are 16A/34D, 22A/24A and 5D/26A. I have answers for 6A/34D and 22A/24A which work, but I can't make anything work for 5D/26A (I initially had two words which I thought worked, but on closer inspection I realised that they didn't).
I can't parse 2D. There are two possibilities for the unchecked letter, but if (as I suspect) this is the single clued entry which provides a further thematic example, this eliminates one of the two possibilities.
