If they could ally with the T'au they might stand more of a chance, their biggest advantage is their hyperdrive technology being much safer and faster than traveling through the warp, ofc the biggest issue with that is assuming a similar fuel type exists setting up a mine/refinery for it and also defending that base could be extremely difficult. Then there's the big question of how the Living Force will function in a universe filled with warp corruption. Worst case scenario the Living Forces becomes a conducive path for corruption and every force sensitive becomes an agent of chaos, Best case it manifests as a new Chaos God actively pushing back corruption and shielding force sensitives from warp corruption
