Your passion vines will do great there. It appears that is a vinyl lattice, and may need some support in the middle. Attach some 2x4 pieces in the centers to even them out and screw the lattice to the new supports.

Although I like the purple incensa variety the best for their fragrance, the Constance Elliott is practically an evergreen. It's the hardiest variety and will not freeze in our deep freeze cold snaps and ice storms. Other varieties will freeze back to the ground, and my experience has been poor for coming back the following spring.

As to the butterflies - well, I leave that call to you. They will wipe out your passion vine.
Here's my results this year with the Gulf Fritillaries this year.....in two weeks time.

It's coming back strong now, but was producing 30-40 white flowers per day and lots of fruit when they struck.
