If Hasbro ever did make an updated Canivac; that's certainly how I think he'd look. Since lately we're doing the whole "Shell and Robot as one" thing with Pretenders; well... you can't do like Bludgeon, Skullgrin, or Iguanus and make the shell the robot mode; Carnivac (as well as Catilla, Snarler, and Chainclaw) would have to be the inverse; with the Pretender robot transforming in the shell as their beast mode. Which might get them some reuses if we got them in Legacy; since we could have Wolfang, Razorbeast, Polar Claw, ...and I don't think there is any other cats that Catilla can become.
...huh... I just realized they could probably double-bill Chainclaw as Grizzly-1/Barbearian since they share the same colors, more or less.
I would love vintage Beast Wars toys recolored in to some new characters.
On the flip side of that, one of my weird dreams is Hasbro releasing recolored Cyberbeasts from BWII as Dinobot, Waspinator (i know thrustinstor is basically this, just bare with me) Silverbolt and Sky-Byte. Make them from some alternate future or different reality, whatever, but they would be neat, bizarre one offs.
Iguanus rules, and looking at his lay out, I kind of want Hasbro to bring back Battle Beasts with his basic construction. Like, throw the other Pretenders at me absolutely, but for ten bucks i think that'd be a great way to work those designs back in to stores.
