Would it be more elegant without the blank pages? 
You could make lily *seem* to count pages twice as fast by 
doubling what \fromproperty #'page:page-number-string delivers. 


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
#(define-markup-command (four-hand-page layout props offset) (number?)
 (let* (
   (two-hand (chain-assoc-get 'page:page-number-string props))
   (four-hand (number->string (+ offset (* 2 (string->number two-hand))))))
   (interpret-markup layout props four-hand)))

\paper { % simple example
 oddHeaderMarkup = \markup \fill-line { \four-hand-page #1 } % Primo
 evenHeaderMarkup = ##f
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

And \four-hand-page #0 would give you even numbering for Secondo.
