Sorry, but this is not feasible.

You will need 25+ Large Storehouses in order to complete the Phoenix Challenge (step 6 of the Temple Challege at Level 68 requires 65,135  ). Given that you will need to generate more than 200,000,000 XP to move up each level in the 60's, space is required for Scooter Stores. I had 74 of these and some others now on Level 70 have had a lot more. If I had my time again, I would use my  for the largest storage I could have got when they went on sale !! Thought the Crystal Storehouse would do it, but ended up having to get two.
