Sounds like you already have an idea of if you are gonna be able to make it with these pieces!
I would recommend you balancing your program with some easier pieces together with these ones. If you are not used to longer performances, or performing in general, it's nice to begin with something that's not too challenging. I often used to begin recitals with something mid tempo baroque. It demands some clarity of fingerwork, helping you wake up your fingers (mine can get sluggish due to nerves) and establish a more comfortable contact with the instrument. It helps a lot to get more comfortable with the situation before you launch into more difficult stuff.
