You can do this in macOS preferences, in the keyboard item.

You mean, map the resulting caps lock, that is, the key labeled "Ctrl", to 
"hyper"?  It seems that, if you map both the caps lock and the control 
keys to "control" in the macOS preferences, and if you add

(setq mac-right-control-modifier 'control)
(setq mac-command-modifier 'meta)
(setq mac-option-modifier 'super)
(setq mac-control-modifier 'hyper)

to your init file, you'll have what you want.
