There are two climbs in reference here that use that anchor. The first pitch of the OW up and right (forgot the name) ends at that anchor and then the 2nd pitch takes off from there, and the end of Karate crack. Problem is climbers have been doing it this way for 20 years. I personally dont have a problem with refitting a new higher anchor but I think you will run into problems.
And this is not the forum for it. you should post your question on Smithrock.com.
