That's actually really neat It makes sense for him being an 8w9 as well. Especially in Heart Of Ice, he has quite a "soft" side. His Bruce Wayne persona is also similar to Bill Gates in a way. If he's my Conflictor that neatly explains why I look up to him so much, and his positive relationship with Superman in JLU. Very nice. Even better is that I honestly wouldn't have thought of that typing for him.
My current theory is LIE. I previously had speculated LSI. But I think his characteristic "planning for all contingencies" m.o. fits better with LIE, an Intuitive type. There are certain similarities with Michael Westen from Burn Notice (whom I type as LIE) -- practical and strategic contingency planning, technical proficiency, the cool and dry professional demeanour. That's my current working theory, anyway.
What type do you think the Batman of the animated series is?
