The future of BW homages will be interesting.
Unlike G1 (which had a cast of thousands and each of whom got either into the TV show or Comics [or both] at some point), Beast Wars had a cast of about 20 characters - IE, those that appeared in the TV show.
Repainting the Waspinator mold into Buzz Saw would be easy enough, but there is little point in my opinion.
Masterpiece and Generations lines in the past have had iconic G1 characters -- characters that people grew up watching and reading. These lines appeal to people that were G1 fans when they were kids and are now being enticed back in with new iterations of their favourite characters.
But Buzz Saw wasn't in the BW TV show, so a repaint such as he is unlikely to entice anyone back in.
Also, G1 had similar models for multiple characters. The Seekers are a perfect example, as are Sideswipe and Sunstreaker. So repaints are easy and more readily accepted. Beast Wars didn't have that. Cheetor/Tigatron and Tarantulas/Blackarachnia were as close as we got, but there would be outrage if Hasbro (in this day and age) tried to simply repaint a Tarantulas toy into Blackarachnia. Their models are too different, albeit both being spiders.
Some are saying that Rhinox could be repainted into his Predacons version as seen in the episode 'Dark Designs', but that is a reference to such a fleeting (and non-important in the scheme of things) event in BW that it's again pointless.
The reproduction of old BW characters like Wolfang or B'Boom into new bodies, while being welcomes by a fan like myself, wouldn't bring about the sense of nostalgia and memory for people that were fans of BW all those years ago. Sure they appeared in the Comics, but really only long-standing BW fans bought them anyway.
Hasbro, if they do wish to produce more BW toys, should concentrate on the main BW cast from the show, and avoid repainting them all together. The rest of the Generations line (the G1/2 bots) will allow for enough repaints to help line their pockets. Leave the Beast Wars guys out of it.
