I guess we are getting into a deep "what constitutes a fakie" discussion here. But I gotta say- that doll is made with the Mattel Kelly body/face mold. No modifications other than paint differences and quality. These dolls were meant to fit in the Kelly line, but as a cheaper, knock off alternative. In my opinion, that means fakie.
The Sweet Scents are their own line with their own molds. They are newer than the vintage SSC dolls that one would compare them to (many came out in the 2000s, removed even from the 90s SSC dolls). While they were cheaper than the bigger brands, and there seems to have been a large production run of different ones (less character branding), they still remain a solid line, with their own molding. They were independent, not reliant on fitting in with a main stream toy line.
Regarding your particular fakie, there absolutely were others in the "series." As in, at the Dollar Store (or KB for more of a mark up) where she was sold, they were using the Kelly mold all over the place, probably in a Disney Princess rip off capacity. The line probably has a name... and it's probably "Princess" or "Princess Dollie" Or "Princess Kelli".
Have you looked in a Dollar General store? I suspect this one might have been a KB run, so no checking that anymore, but if it was DG, they could be on shelves right now. Which Kelly fakies they have at any particular time changes- sometimes they are just using the Kelly mold head on a fatter, cheaper body, other times the whole Kelly doll (like the one you have pictured). Might be worth a look if you are really curious.
