I do suspect a lot of people want B/X but with paladins and demons and maybe spell disruption or 18/## Strength or 1d8/1d12 (s-m/l) longswords -- heck that's how a lot of us who started with B-BECMI played AD&D BitD quite a bit.
As for specialty priests and kits -- I'm surprised there aren't more OSR attempts at the same thing, but unsurprised there aren't a lot of retroclones or the like. I think there was a lot more love for the ideas of kits and specialty priests than the specific 2E implementations. Those often ended up hitting too low, too high, too specific, or just kinda out of left field.
