Something I remember proposing more than a decade ago. But it's actually better to use it as an anchor for a station at the L1 earth-moon point and one-shot payloads there by ecannon from the lunar surface, since at the right angle such payloads actually climb up the gravitational saddle to the saddlepoint where the station is and come to rest there.
