The solution to having your dodge restricted by an armor's dodge cap is to not wear armor...
Switch over to outfits or robes--many still have decent AC bonuses on them--plus if you're max DEX anyway, will keep you from having that cut off as well.
I would also--as others have suggested--pick up or craft a blurry item (green steel accessory with a displacement clicky and skill boosts works, Ring of Shadows Heroic Elite or higher, the bracers from the Cannith challenges...) and a ghostly item (there's a cloak from Tempest Spine that also comes with a green slot on it. List here:
