no friggin' way!
I have done similar things. In high school and for several years afterward we used to go rock climbing 2 or 3 times a year. A favorite spot was Seneca Rocks State Park in West Virginia. It think it was around 1,200 feet to the top. A friend of mine has (or had) a shot of me that I keep hoping he will find. He was about 15 feet above me and said "smile". In the shot, I am looking up with both hands and one foot on the rock, and over my shoulder it is about 800 feet straight down to the treetops. No ropes. We always free-climbed because equipment was too expensive. Ah, the brainless invincibility of youth! Luckily we all survived. Would I try it today? HELL NO! I like the ground thank you.
