Anybody come across pond apple hybrids?

[BayAreaMicroClimate]

Just found this video I think claims pond Apple and sugar apple “atis” ? They have different flower types so is that not possible? Does it have to be same flower type to be hybrid? I have Toptropicals Annona Sp which they think is Pond Apple and soursop? Some people think it’s just pond apple. So my main question is do you think it’s possible to make a not so tasty fruit improved with crossing it with other related species? Just like how Babaco was created? I’m also hoping people improve mountain papaya varieties in the future
