Mapping a single keypress to a chord

Heh, I’m looking to do “hyper” as my own modifier (shift, ctrl, alt, command - I map this non-conflicting custom super-modifier for my own OS mappings). I took a shot at it, but it’s not compiliing:

LSHIFT(LALT(LGUI(LCTRL())))

I must be close, but need a hint!
