#1 WWE NXT Horsewoman Charlotte Flair
This is the easiest and most obvious potential feud for Tessa Blanchard if she opts to sign with the WWE over AEW and other companies. They represent the only two major female professional wrestlers that are daughters of the Four Horsemen (Ric Flair, Arn Anderson, Tully Blanchard, Ole Anderson).
The fourth spot in the group was always a revolving door with the Horsemen, as the likes of Barry Windham, Sting, Lex Luger and many others can claim to have been members of the infamous faction.
Outside of Becky Lynch, Charlotte Flair is always booked as the top female Superstar in WWE. She has won at practically every WrestleMania she has competed at and she wasn't pinned in the main event of WM 35.
WWE books her so strongly that they already consider her a 12-time champion. They even started to add reigns as NXT Women's Champion to that total, just to fast-track her to break her father's record of 16 world title reigns.
Tully Blanchard's name isn't treated on the same level as Flair's in WWE, but he's still one of the most infamous wrestlers of his era. WWE loves to book family feuds, as evidenced with Flair's feuds with Natalya. We can also look to the current feuds on SmackDown involving Roman Reigns and Jey Uso, as well as the Mysterios.
Family business is usually easy to book, due to real-life situations and history in the business. The lineage of their last names would write the feud itself, but it would likely mean that WWE would have Blanchard lose out to the Queen. Would she be willing to fall?
