That sounds like a very good plan. Laying out the strobe stripe will be a bear, though. I think it's important to mock that up with the rest, because I think (gut reaction, again) that the treatment of the strobe, the way the individual stripes are broken up, is the primary thing that won't work well with the others.
Re: the side stripe with the bumblebee, if you look at the box for the 70 Challenger from AMT (the original box from about 25 years ago), it has a combination that's roughly the 70 side stripe flowing into the bumblebee stripe. I actually always liked that look on the model, but I know a lot of others didn't care for it.
