The main similarities between Shere Khan and Sienna Khan are the names, and Bagheera and Ghira are the names and the abundance of black fur (assuming he's a cat faunus of some sort as well).

Though, to be honest, that's all you need for an allusion. Allusions aren't meant to be direct ports or perfect recreation sin the setting, they're meant to be small nods to a reference point but ultimately their own character. That's why Weiss wasn't being hunted down by someone who was ordered to cut out her heart and bring it back to the Evil Queen (would that count as Sienna in this case since the White Fang are the ones more likely to want her dead?) to prove she had been dealt with. It's why Ruby hasn't been on a trip to visit her grandmother, and Yang hasn't been a kleptomaniac who breaks into peoples homes (though she did break a nightclub).
