I completely agree, PT-17/N2S-3 Stearman in 1/32 would be GREAT.
I'd also like Waco UPF-ZPF series. Any cabin Wacos. Navy N3N would also be nice. Ryan ST-A or ST-R.
The Staggerwing sounds great too. Scratchbuilders too rare and expensive. Staggerwing Museum Foundation kit is poor. I've built one and it takes MUCH scratchbuilding. I have two in my stash, but haven't tackled them yet.
