I hate to say this but really, probably the only way you are going to find out whether there is a fit between yourself and Guo Laoshi to simply to go and visit.
My understanding is that he does not charge money but will decide where, when, and how you might fit in---you might not like that and it would certainly be a waste of your time if you felt that way. On the other hand, he isn't controlled by commercial interests and in one sense can form a more profound student/teacher relationship if the chemistry is there. I think that scares the hell out of some students in that they simply have no control over how when and if they get the material---in one sense not everything is a monetary/contract exchange.
Having spent some time in the Wutang group under Tony Yang, qi and all of the aspects regarding its potential application in Liu Yun Qiao's art are there but really not necessary for learning the art---structural alignment and work deliver the goods under the eyes of a good teacher are what you need..
Sometimes if a students gets to hooked into the traditional Chinese framework, they over intellectualize their practice which is something Liu never did---better to be ignorant of the theory and practice than to know the qi constract and try to think your way through the training---there just isn't any substitute.
Its better to spend 3 or 4 years in the basics and generally ignore the qi framework. Perhaps once s student experiences the power/training, then the framework makes sense and stays in its proper perspective.
Good luck
