What do you think of this idea to decorate a bedroom?

so for my room, i'm going to decorate it with very eclectic decor. i'm painting the walls this tan color that has kind of a pinkish hue to it. but i thought about having a signature wall on one of the smaller walls in my room. lilke so friends can come over and sign it with markers and i can write quotes and stuff i like on it. if possible, i would like to do it so the writing is somehow erasable. what do you think?
