You probably won't find many folks in the homebrewing/beer geek community who think too highly of MAB let alone would brew a clone of it. It's really looked at by most as a Macrobrewer's attempt to re-coup the steady sales decline of BMC lost to the craft beer industry by foisting a pseudo version of it on mostly the gullible masses.
Now having said that, and not picking on you fro enjoying it, have you tried other, more representative versions of that style? If you have and they taste similar enough to MAB then you may have an easier time finding clones of those, or just that style in particular.
Then all you would have to do is to figure out what makes the Mic version different that you like about it- is it sweeter than the other version? Then adding lactose to the other grainbill may be what it takes. Is it dryer? Maybe they use a rice or corn adjunct in it. Is it hoppier or less hoppier than the others?
SO then when you figure that out you can kinda figure out what you need to do.
When I am creating a recipe for a new style, I do something similar, look at several recipes online and see what grain was pretty standard to all of them, same with hops, and yeast. And then go from there.
