I have never used that many pallets to build anything. But I can tell you that stripping down pallets is not easy! LOL LOTS of tearing out nails and it IS a pain in the rump. But you have the patience, anything is possible. I don't see why you couldn't use the same plans and with the size they have you using, you could double the size with twice as many pallet boards.
Good luck!
