ugh, just tried this and still doesn't work.

(define-key key-translation-map [?\H-8] ?\◇)

am giving up at this point.

in case anyone's interested, i'm trying to make hyper key do unicode
symbols.
Ι have it all working by
(global-set-key (kbd "H-3") (lambda () (interactive) (insert "•"))) ;
bullet

but yesterday i got smart and thought i'll re-write them using
keyboard-translate instead. (just had a major refactoring of
my .emacs.)

possibly i'll file a bug report. Thanks for the helpful answers.
