Retesting the words like that does find some: REPAPER/5305958597, DUD/2551, DID/2239, LEMEL/5105267, PEEWEEP/4683479543.
With this hackish code to interpret the text as base 26, rebase that to base10, test primality, I can't test the sentences (I think it might be overflowing on the higher value words, even). I think it's not so fun if the base 10 numbers are not palindromic.
Thanks for trying! I was thinking of creating a set of digits for base 26 using emoji or other Unicode characters. Then the numbers would at least look like palindromes. But I don't know how interesting palindromes in an ad hoc character set would be.
