I'd be interested to see how SMIE handles it.
I.e. something along the lines of

  (defvar lisp-loop-smie-grammar
    (smie-prec2->grammar
     (smie-bnf->prec2 BLABLA)))

  ...whileindenting...
  ...(if (head-is-loop)
        (let ((smie-grammar lisp-loop-smie-grammar)
              (smie-rules-function BLEBLE)
              (smie-forward-token-function BLIBLI)
              (smie-backward-token-function BLOBLO))
          (smie-indent-calculate)))
