Let's see, what are Rare's level archetypes and have they already been done in Yooka-Laylee?
Ice stage (DKC, DKC2, DKC3, BK, BT, DK64, YL) - Check
Industrial (DKC, DKC3, BT, DK64, YL more or less) - Half-Check
Jungle (DKC, DKC2, DKC3, BT, DK64, YL) - Check
Pirates (DKC2, BK, BT, DK64, YL hinted at) - Quarter-Check
Swamp (DKC2, BK, YL) - Check
Spooky (DKC2, BK, BT more or less, DK64 more or less, YL more or less) - Half-Check
Cave (DKC, DKC2 more or less, DKC3, BK, BT more or less, DK64, YL more or less) - Half-Check
Castle (DKC2, DKC3 more or less, BK hinted at, BT hinted at, YL more or less) - Half-Check
Lava (DKC2, BK hinted at, BT, DK64 hinted at) - Not yet
Personally, I feel the ice theme has been done to death, and cave levels (unless they have a secondary theme) are rather boring. The one classic recurring theme I can think of that YL didn't even hint at yet is a lava world, although those - like caves, are a bit bland to me on their own. I'm a tad disappointed at how the spooky level in YL was treated, with the spookiness demoted to being a secondary, barely flashed-out theme. My other favourite theme are industrial levels, and I feel neither YL's hub nor the marsh level sufficiently explore that either.
