I took out all trays except for the one that holds the boards. Replaced them with a slim Artbin Super Satchel to hold all minis, and the Lord's of Middle Earth and Warriors of Middle Earth boxes (insert removed) to hold all cards, tokens, and upgraded bits (Fubar Awol's strongholds and replica rings).
It all fits nicely in the outer box once the trays are removed. I really wanted a one box solution.
I'd love to see photos of this if you feel like posting some.
