Thanks! It really could couldn't it? Uru is usually depicted with having a 'stripe' or 'diamond marking' which she would've passed on to her granddaughter. timeline-wise it could work, she would've been younger than Simba and Nala. blood-wise there would be a little bit of an issue as Kovu and Kiara would be cousins but that's ONLY very distant relation. It would also make more sense if Nuka, Vitani and Kovu were Scar's grandchildren. Nuka has the same 'frame' and 'dark fur' around his eyes. Even the same 'mane' but more scruffy. Vitani has 'dark fur' around her eyes and 'scruffy' eyebrows. Kovu however shares many traits with Scar. Green eyes, dark-purple reddish fur. But since their colors are different shades but much too similar, him as Scar's grandson and heir makes a lot of sense..! And lastly, Zira. She's practically a sarabi-colored female 'Scar'. But some of her traits are Pridelander-like such as, her 'white rings' bellow her eyes. But her upper 'eyebrow's and 'eyelids' have that 'sharp and angular' edgy feel that Scar has. Her 'dorsal stripe' in my opinon makes her look like a real lioness and even her movement, regardless of her unrealistic paw-gestures xD She also has 'red eyes' which seems to be the 'dominant gene' in TLK universe. Mufasa has red eyes, Sarabi has orange, but Simba's are red. Nala has green eyes, Simba has red. Kiara has red eyes. Even Kion has red eyes but takes more after Mufasa which I love. So yeah it's not THAT twisted. Though I wish there were more pics or fanfic of it It's such a unique and different theory and you don't hear it very often. but if anyone has a problem with it then they're just going to have to deal with it. Besides people nowadays have Zira as Mufasa and Scar's sister, Kovu as Scar's son or Vitani as Scar and Nala's daughter, even Nala as Scar's daughter. (I like the 'Vitani' one though as it explains her fur-tone which is similar to Nala's and even the blue-eyes.) So yeah, it gets boring using the same 'Zira as just a fan girl' of Scar or Nuka is 'apparently' not Scar's son and was just sired by a random male. :p anyway thanks for commenting!
That also is a neat theory! They do have similarities after all. E.g Red or orange eyes, scruffiness at their ear-rims and the bottom rings below their eyes.. If Scar and Mufasa are brothers despite their appearances, then Zira and Sarabi can be sisters. They're practically the 'parallel' of Scar and Mufasa..
