I've always thought of HL projectors being a prism-like gem attached to a small power source, focussers and appropriate housing, in the case of the equipment being HL entirely then the projector is like a trinket or accessory that projects the equipment or shape it needs to when turned on. Entirely HL underwear? You actually wear a belt, which then projects the HL underwear, or as per the subject of this thread a strapon. HL bra? Necklace that projects the bra, that sort of thing, you know?
In any case, I'd think it would be in the realm of technical possibility but you'll be faced with the issue of who's willing to go through whatever rewrites necessary and, most importantly, the code rework.
