I'm thinking of the ones from the Dragon Mounds (http://elderscrolls.wikia.com/wiki/Dragon_Burial_Mounds), they can only be encountered between or at certain points during the main quest. Then they vanish off the face of Tamriel, presumably to pester other provinces.

Don't know if this has already been done but it would be great to hunt down the named dragons raised by Alduin if they are missed during the main questline. They appear to just fly off if not encountered and it seems highly likely he's raising them for a purpose other than random mayhem.

Was thinking more like those Centurion Crossbow things the Dwemer Centurions/Spheres carry. Could be a fast firing, low damage repeater or a slow firing high damage manual re-loader. Been looking for a DragonSkull Shield too but no luck.

also daedroth, mountain minotaurs, ogres, killer whales, dwemer sentry turrets, daedric dragons and more ghosts/wraith type creatures.

I'd like to see clockwork based repeating crossbow pistols as well, low damage but rapid fire style fire fights.

Maybe, as you were saying, condense some of the tree's into one but keeping the structure intact. For instance, if the first perk point is free, it could go :- Fighter (free) - can use weapons ____ Armsman - on to rest of 1 Handed Tree l__ Barbarian - on to rest of 2 Handed Tree Guard (free) - can use armour ______ Agile Defender - on to rest of Light Armour Tree l__ Juggernaut - on to rest of Heavy Armour Tree The only problem would be if there's a limit to the number of perks slots in a single tree.
