The hood looks good! Perhaps VZ will consider using their mould for a cf piece if asked to do it.
About carbon vs glass. Mixing the two isn't only the moneysaving compromise you might think. A good mix for a hood would be two layers of 600 g/m2 carbon with a thin layer of glass in between. If you end up in the wall there is a good chance that such a hood will stay in one piece, kinda like the windscreen, instead of shattering in a million pieces. Kevlar would do the jod too but it is a pain to work with (although for a hood it should be ok).
I'm now looking for a stock hood that I can use to create a mould for my cf hood. I will make it as a lid (but it will have a reinforced underside in the correct place so that the seals will work) to be held by pins but it should be adaptable to the stock hinges if I want to. I plan to make it as I described above and it should weigh no more than 10 lbs (without clear coat).
The biggest issue now seems to find a cf carpet that is wide enough since I wanna lay one piece layers. So far the wider carpets that I have found are twice the price per gram compared to the normal width.

Actually, carbon isn't really that hard to work with. See someone do it once and then you can do it too. Even though carbon fiber is far from cheap the biggest reason for parts being expensive is that it is labour consuming. With the new user friendly epoxis you have a long bucket time so it is no stress, they are shrink free and you don't need an owen for baking in order to get the parts to be able to withstand higher temperatures. Heck, they're even free from spirits so you don't even need a mask while working with them (or so they say). Dust from sanding should be avoided though but I wet sand so it is not a big deal.

I thought C/F had to be baked in an autoclave in order to cure???? Has that changed or are there different grades of C/F?

It has nothing to do with the carbon. It is about the epoxi. For use in high temperature environments it is good if you can bake the cf part in an owen as that process will increase the temperature resistance of the epoxi. However newer and better epoxis are here and they are able to stand temperatures well in the 150 degrees Centigrade range despite being cured in normal room temperature. And in addition to this they are also 100% shrink free.
