I think she can qualify, on the first half of semi 1 she and Alessandra are the only female singers, so she will stand out, the song has an intergenerational appeal and a more, let's call it, "old eurovision" song may gather the votes of the public that typically doesn't enjoy alternative styles of music and in a semi filled with that maybe she can Viktor Crone her way into the final.
What worries me is the running order, I can see it being a great opener, the end just pumps you up for what comes next, but it opening the show could also be a way to lose the public that tunes to the show a bit late and a lot of votes.
My ideal placement would be right before Käärijä, "Ai Coração" literally ends with "cha cha cha" so it would only make sense to have him performing next and although Finland doesn't really need it, the contrast would help both songs stand out.
The staging needs some work, but she has a solid concept and things can be polished and perfected for Liverpool, the portuguese delegation have been doing a good job in the last 2 years and I'm hopeful that things will be much better in may.
