A light rail system over Sepulveda Pass would probably require drilling a tunnel. Early estimates are at least $6B: http://www.latimes.com/local/lanow/la-me-ln-sepulveda-pass-t.... It could get built, but I don't think the final price tag is going to put the lane expansion to shame.
Buses can already use the HOV lanes. One of the expansion lanes (the northbound one) was an HOV lane, so now there are HOV lanes in both directions. Who cares, given how few riders buses attract.
