Needless to say, i'll follow you on this one.
I'm planning to do Alphas too, but it will be my first try doing this kind of stuff and i'm still gathering informations about.. well about everything.
Not a smart choice for a beginner like me, but it has to be my first one.
Looking forward to see your work, good luck!
p.s.: on a quick note, the revoltech has a couple of things that are different from the actual suit: there's no cross on the gloves and the pectoral armor is slightly inaccurate (i actually prefer the revoltech one, but if you're looking for a perfect replica of the suit in the manga the image below will show you the difference). The helmet seems to have some scaling issues too.
Edit 2: i've found another picture with a different pectoral armor, more similar to the revoltech, but as far as i can tell it's the first suit with the second version of the helmet.
