Aaaand 

Manu12 takes the lead! :D
There are some ideas i can drop off right here; i have too many ideas for myself anyway.
1) Tangled Isthmus, but significantly larger (longer rush distance), and with all mexes accessible via fords (depth -6..-8, so ground units can move) and with flat islands on the sides. Generally Tangled is a "split personality" map with hard lanes; i imagine it redone as a properly mixed, non-cheese map.
2) Same treatment applied to Finn's Revenge. Connect islands with fords, bring them closer, make the beach crossings in the middle ship-pathable (-6 again), add a few extra paths for ground units, make sure the beaches are all hover-pathable. Maybe add some spider cliffs. Maybe make much of the middle lake shallow.
3)

Jasper suggests remaking Arctic Crossing. It's a very cliffy sea map, which could be interesting if. Guess what. The cliffs were connected via shallows, making it a sea vs spiders map.
4) More Wesnoth maps!
Thornford is secretly a reimagining of Wesnoth's map called Isar's Cross. There's more where it came from!
