I am building this set both ways and having a blast with it.
A number of the cards, beyond the checklists and teams, do not exist with purple sky variants and didn't have the red ink adjusted during production. So I think you can cross off a number of them on your list because they do not exist.
Cards I believe that do not exist with a purple sky are: 12, 14 (Brown), 18, 19, 24, 25, 36, 38, 48, 49, 50, 51, 54, 58, 59, 60, 68, 72, 74, 75 (Meredith), 79, 80, 83, 84, 85, 90, 97, 103, 109, 117, 121, 123, 125, 129, 130, 133, 140, 145, 146, 147, 150, 151, 152, 153, 154, 155, 156, 157, 160, 161, 162, 166, 169, 170. Purple skies are not rare, similar to 1962 baseball series 2 green tints. If one hasn't appeared by now, the odds it exists are miniscule.
Don Bishop I have a very hard time telling apart, but that might be just my eyes. Unfortunately I need both Lilly's still
