Took me a bit to figure out how to approach it, but after that it was pretty smooth sailing. Wonderfully clever construction, thanks a lot for the fun puzzle!

Very cool and surprising puzzle.
My normal way of doing palindromes went nowhere and I had to restart couple of times, until I figured out how to approach the puzzle correctly.
Many thanks, one of my favorite solves this year :)
Deserves much,much,much higher rating.
