You can try posting on the AC forum...but MLL passes are in very short supply. However, they're a pretty friendly bunch and if anyone over there will be at T1 at the time/day you're there, I am sure they'd invite you in as a guest.
Otherwise, not T1 alternatives. The KL lounge is both Priority Pass and pay lounge, but one must have an international ticket to get airside. The AA lounge can be accessed with a day pass purchase, or Priority Pass membership, but you must have a valid US-bound flight ticket to get airside and through US customs/immigration.
