I’ve actually drawn a picture at one time of what
Sally and Bunnie* may look SEGA-ized.
And yet, I don’t think it’s a good idea whatsoever.
Personally, I liked the SatAM series (I swear to god I’m not one of those creepy furries), however, I believe the elements of SatAM should stay where they are. In SatAM and … well I guess their bastardization, the Archie comics.
… Which I suppose brings me to my point. The Archie comics try to combine every aspect of Sonic into one big clusterfuck, and it sucks (not so much nowadays, Ian is actually capable of writing).
Trying to bring Sally into the SegaSonic verse (yeah, I refer it to that, as well, there’s a lot of different aspects of Sonic and it helps to prevent getting things mixed up) would probably be a disaster. As said earlier, everything about her would have to be changed to some degree or another.
Princess? Gotta go. We already have Elise and… possibly Blaze depending on if prescribe by Sonic Team’s Bizarro retcon. Don’t need another princess in the SEGAverse.
Design? Would have to change, and a lot of fanboys (and girls, but mostly fanboys), would be pissed on that alone.
Personality? Her personality works in the post apocalyptic SatAM world, where her bossy attitude is easily explained as necessity, but it wouldn’t work in the bright and by comparison cheery SegaSonic world. Thusly, that too would have to be changed.
By the end, like previously said, she probably wouldn’t even be the same character anymore other then name, which even then would probably be altered slightly.
*Can't find that particular image at the moment. It's... somewhere in the great abyss. I think Jamie may have it...
