Haven't tried it personally, but have to say I am very suspicious. Leleupi are fairly high on the aggression spectrum, while paracyps are about the most calm, peaceful fish you'll find. It just doesn't seem like a good mix.
Even if the leleupi don't brutalize/kill the paracyps, I just can't imagine the paracyps will feel comfortable.
