That would look like this (you want to add the missing greek letter
names):

(defconst crucible-mtksy-keywords
  `(;; Greek
    (,(rx "\\" word-start
          (or "alpha" "beta") ;add the other letters here
          word-end)
     (0 'crucible-mtksy-tfc))))

The result will be a slightly optimized regexp (equivalent to yours of
course).

If you want to go that way, I think it would also be possible to avoid
the repetition of uncapitalized followed by a capitalized letter name.

HTH,
