No but I would buy the fuck out of one.
This is prob the closest thing- https://www.amazon.com/Rebel-Princess-Guide-She-Ra-Tracey/dp/1338556215/ref=mp_s_a_1_5?dchild=1&keywords=shera&qid=1621550469&sr=8-5 but it’s nothing super interesting.
Noelle posts on Twitter frequently, and I view those as “official” art sorta.

Yup, they are long gone from Targets here. We bought SheRa, Glimmer, Bow, and Adora (and the costume and sword/shield set) when they first went on clearance. They were ~8 on clearance. Never saw Catra after it was obvious they weren’t getting more (and actually only ever saw her once).
They are absolutely not worth the prices I’m seeing online right now, but I’m very happy with the price we paid for them. There’s one on US Amazon for $44, it’s still way too much (they were originally priced at $14), but I don’t think I’d be angry at myself for buying that if it was nostalgic for me and I wanted to share that with my daughter.
A much cheaper alternative might be the little toy that was at Sonic, not really a play doll, but certainly playable. There’s a gold one, and a Hordak as well. Probably easier to find and have shipped to you, too. IMO, it’s cuter in person. - https://www.ebay.com/itm/2020-Sonic-Meal-Toy-SHE-RA-Princess-of-Power-3-5-Action-Figure/124278572628?hash=item1cef948654:g:MqcAAOSweyZfIeSd
This book is also really great for that age range- https://www.amazon.com/Rebel-Princess-Guide-She-Ra-Tracey/dp/1338556215/ref=mp_s_a_1_12?dchild=1&keywords=shera&qid=1598745525&sr=8-12
If you see this costume or the matching sword for a price within your budget, and your daughter likes dress up, I highly recommend, my daughter still plays with them and the costume still fits (she’ll be 8 in a few months but she’s very slim) - https://www.ebay.com/itm/DreamWorks-She-Ra-Princess-of-Power-Dress-Up-Set-Halloween-Costume-Childrens-Kid/124311392313?hash=item1cf1895039:g:uAIAAOSw6EhfRKCb
They clearly weren’t sure who to market this show towards merchandise wise, and I think we’re unlikely to see much merchandise now. I’ve bought a number of things on Etsy, stickers and such, might be fun for your daughter.
