I'm not sure but I think that bo198214(Henrik Trappmann) had this idea in 2008 http://math.eretrandre.org/tetrationforu...l+function

With his idea we can reduce the problem of real-rank hyperoperations to an iteration problem

Later this idea was better developed by JmsNxn (2011) with the concept of "meta-superfunctions"

I'm still working on his point of view but there is a lot of work to do...
