I've asked about this before and, from what I hear, it's definitely something people want to do, but it's a big risk, financially. I mean, since we don't have access to a cam R&D facility, we would have to design such a set completely based on what specs would be theoritcally ideal. The closest we could come to "testing" such a cam set would be Luke being generous enough to throw ideas into the Desktop Dyno to show us what they "should/could" do on paper so to speak. What happens when we actually have someone drop $500 or so on this set of untested, completely custom cams and they don't do shit? That's a lot of time and money down the shitter imo.

As for the 4G63 specs, I'm no expert, but considering how different manufacturers use different methods/guidelines for measuring specs, I don't know that just copying the 272s would translate well for the 420A. Besides, those cams were designed for the flow characteristics of the 4G63 head, not ours. Then again, I'm no expert, right? :P

Just my take on the subject. I would love to see some custom cam specs discussed. Something nasty that would work with larger turbos on well ported heads. }(
