StimpsonJCat - I have also seen these two listed together on Compatibility charts, if you look at the compatibility charts they are not specific. An Example, it says Y to Lions and eels but really there are very few eels a lion can be housed with, it says C (Can co-exist with Caution) with triggers, Y to Puffers and Angels. It is a Basic Chart that does not Specify.
I can not tell you the countless threads I have read over the years about Anglers and Lions, Triggers and lions, Eels and lions, and I am sure AW has read their share of them also. However I did go and look for a few quotes from others, though I can not put in the links, I hope the quotes will be allowed.

"I have had frogfish eat lionfish that were as long as they were, and there are reports of sharks, coronetfish and groupers eating lionfish. I have also seen larger angelfish, triggers and puffers nip at lionfish fin spines. Just because lionfish have a potent defense system does not mean they are invincible to attacks by other fish."
"Beware — not even the venomous spines of the scorpionfish will deter frogfishes from eating them if they are small enough. I have had several frogfish eat my lionfish, with no ill effects to the gluttonous antennariid!"

"Frogfish are extremely specialised piscivores (fish-eaters), with several extreme adaptations that help them catch their prey. They eat any fish they can successfully catch, and their mouth can extend up to 12 times its size to engulf larger prey items. They have been known to eat lionfish and scorpionfish without any ill-effects."
Frank Marini
"Even though lionfish are venomous, lionfish are not immune to being harassed or even eaten by other fish. Large eels, frogfish and other scorpion fish are all predators of lionfish in the wild. According to Michaels (1998), large angelfish, pufferfish, and triggerfish are also known to harass lionfish. Triggerfish are notorious for nipping off the dorsal spines before killing lionfish."
