There are 5 things for which Naruto Uzumaki is well known. Pranks, Orange, Kyuubi, Rasengan, and Clones.Let alone wants to spend all his time making portable showers.
Of course, all those memories might be boring, so I had to go back and check — apparently he doesn't get the chakra back from the Elemental Paperwork Clones, but there's no indication that they don't give him the memories. Dumping out a bunch of clones who could make seals and then not give him the memories would have been a neat solution.
And, if he pairs up with Tazuna, he might be able to expand it from "Portable Shower" to a full "Portable House"!
