South Americans Carabajal and Ferreira will consider themselves serious world title contenders.
Argentina’s Carabajal is still only 33, and her only defeat in 23 fights was by Taylor in 2022.
Ferreira, 31, is another who is improving with experience fights for the vacant IBF title later this month before focusing her attention to representing Brazil at the Paris Olympics.
But it is London-born Dubois, who holds the IBO lightweight title, who many have tipped to succeed Taylor.
Dubois has been backed for greatness since bursting on to the amateur scene as a teenager and competing at the Tokyo Olympics. Her perfect professional career so far has so far given substance to the high praise.
At 23 years old and with five knockouts from her nine-fight career, she has time and power on her side.
Skye Nicolson, the newly minted WBC champion at featherweight, has been watching Dubois since the amateurs.
“A crafty southpaw, she’s very physically strong for the weight as well, she is very hard to beat. I think you can say now she beats everyone in that division,” she said.
“Her toughest test will probably be Beatriz Ferreira, I think it is competitive between the two and that is a super-fight down the line in the women’s division.”
Warrington’s Dixon has been inspired through her career by Taylor – but is not overawed by the possibility of stepping to her level.
She proudly calls herself an “anomaly”, having come from white-collar boxing to compete for a world title on Saturday, and says that unusual background is a benefit.
“They all had a lot of amateur background, or these superstars who went to the Olympics,” she said of her lightweight peers.
“I’ve shown girls you can start a sport later in life, and if you put all your effort into it you can excel. It’s important to have people in the sport from different backgrounds, showing you can do it too.”
