Did Arkhan the Black open the gates for other LLs with units from other factions?
Morathi can be one example of them, getting access to Slaanesh unit Daemonettes and the Hung unit, reskinned Norsca/Chaos marauders.
From Warhammer Fantasy RPG 2nd ED -- Tome of Corruption
The recent strain of a continued war effort against Ulthuan has driven Morathi into deeper wickedness. She believes ancient artefacts lay hidden within Lustria and that to crush the High Elves for the last time, she must recover these relics. Morathi gathered a coterie of Sorceresses for a mission to the Chaos Wastes. Mounted on Dark Pegasi, they flew across the land to renew their ties to Slaanesh and take control over the Chaos tribes of the Hung.
When they arrived, they found the Hung waiting, weapons bared but unwilling to confront the beautiful women because of the raw power that emanated from them. Even the Warlords, who rose from their council to face the intruders, were halted by the cries of their own Sorcerers who knew Morathi had the favour of the Pleasure Prince, Slaanesh, whom they knew as Shaarnor. Morathi, after a spectacular orgiastic ritual, summoned sixty troupes of six Daemonettes and sent them to wipe out the Hung's rivals: the Kurgan. The Daemonettes crossed the distance and tore apart the Kurgan, sending them fleeing to the west, and the Hung swore oaths of allegiance to the Sorceress, thus putting an end to their raiding of the Dark Elf Lands.
Morathi returned to Naggaroth at the head of her new army, intending to lead them into the foetid jungles of Lustria in search of the treasures of the Old Ones. She explained her plan to the Witch King, claiming that she would recover wonders and weapons that could surely be turned against the High Elves. Her success or failure in this effort has yet to be recorded, and the implications of the spread of Chaos remain to be seen.
For those who dont know who the Hung and Daemonettes are

2 · Disagree AgreeShe had fought beside Aenarion in the days of her youth, killing daemons, slaughtering the enemies of her people with wild abandon. She had cast spells and brewed poisons and worked out battle strategies for his armies. She had used her gift of visions to grant the elves victories innumerable.
The so-called high elves had forgotten that now, preferring to cast her as the villain in the simple-minded morality plays they so enjoyed since her son had sundered the realm. They had no idea what it had cost to win those battles back when all thought the world was ending, or the price she had paid for victory.

"Hawk no longer. My wings are dust and bone. I crawl through time now, like an asp."
"You took my wings, Neferata. You made me crawl. Now I return the favour. Crawl, cousin. Crawl."

For ease of memory, if we're not talking about cavalry, everything the High Elves have is better than everything the Dark Elves have.

The eaves will sing no more;
The waxen ground will keep you bound,
Death-pale until the thaw.
Then she placed the rest of Orion's ashes into the bowl and turned to face the Oak of Ages.
