I'd like to see those guys in the CS line too but let's admit it - its way too late already for Jakks as Mattel takes over in 2010. Hope we get those guys, plus Macho Man, Owen, Steamboat, etc, via Mattel next year.
I always wondered why we never got Bravo in Hasbro and LJN since he had a pretty big role when he was around so that made me want him more in the CS line.
It could also be that he didn't approve having a figure made. Some of the old-school type guys just didn't like the idea of having kids play with a "doll" of them and, if they didn't need the royalty check (and Bravo did have...ahem...other streams of income), they didn't sign off on having the figures made.
Also, I think the company just didn't deem some guys marketable enough to get a figure. Come to think of it, I don't remember ANY Dino Bravo merch ever getting made (besides trading cards).
