nice work! has this cross been attempted before?

I'm not sure if it's been tried before. I have 3 small plants growing now. The seedlings are just beginning to look like passionflowers but it's still hard to tell which plant they resemble.
The other successful cross has been P. vitifolia and P. incarnata. With P. Incarnata as female, every single pollination has produced fruit. With P. vitifolia as female, the percentage of successful pollination is less. If you own both of these you can successfully produce some fruit on both plants. I just harvested a fruit from P. incarnata x P. vitifolia pollination and it was delicious, tasted like banana/pineapple.
