I didn't have a quick application like yours to test since haven't used 
beam settings but I was just trying to help you understand how variables 
work so you could create your 'posBeam' (or whatever you want to call 
it) definition from the padText example.

A quick attempt (completely untested) would be

    posBeam = #(define-music-function (parser location num1 num2) (number? 
number?)
    #{
      \once \override Beam #'position = #'( $num1 . $num2 )
    #})

Without testing I don't know whether you would apply it as:

\posBeam #3 #2
or
\posBeam ( #3 . #2 )
or something different.
