If you're going by Golden Age rules, there was the time when Namor was fighting the Torch that he flooded all of Africa. It was OK though, because Ka-Zar saved all the animals by having them go on a mountain.
I kid you not, that happened. Pretty sure it doesn't count as canon today.
Yes I am pretty sure that does not count as well.
Wakanda and Atlantis have millennia long histories so it is very possible they have come into contact before. A Namor/T'Challa mini could explore some of their kingdoms history together. If not for AvX I think a Namor T'Challa ongoing would be great. Both their personalities and power sets compliment one another. And while T'Challa will always be number one with me, Namor is in my top ten, if not top 5.
Reality is for those who are afraid of science fiction.
I'd prefer a mini about Bahenga founding Wakanda & rest of the tribes/cults history aswell..
Or a mini that shows more T'Chaka as start at being BP & King, along an ageing Azzari the wise, Nanali & N'Gassi reacting to his rule.. Also could show what a younger S'yan, Zuri were up 2 & show T'Chaka dating/marrying N'Yami..

Hickman would do well. I think it's because despite the problems with NA he will commit to delivering a complete an comprehensive story. I think Deo would do the job masterfully. Even Epting, mike Choi. Perkins? I know there is someone Im leaving out here.
I would love that, heck with how hold both titles are I wanna see if theres ever been a Black Panther to hold the title Iron Fist, since well despite being overkill it would be awesome. If it did happen I know I'd just be waiting for T'challa to call on that Panthers abilities.
I think Jonathan Hickman would be a definite candidate but I'd also be partial to Al Ewing who's definitely proven that he gets characterization right. The fact that he respects continuity is really essential for a character like T'Challa who's been disrespected by a number of other writers.
