Principally yes; a drawback of the following hack is that it doesn't
abolish the leftmost vertical rule of each system. If you can do without
this rule at all, it should work fine with the command \nostartrule
included. Please take the following as an example.

% Here comes a bunch of rather general macros which enable printing or
% hiding barlines for each staff and inter-staff space individually:
%
\makeatletter
\newdimen\barline@depth
\def\rul@indiv#1{%
\n@loop
\Comp@High
\expandafter\ifx\csname s@bl\number\noinstrum@nt\endcsname\relax
% Taktstrich durchziehen -> Tiefe ueberbrueckt Platz zum vorigen System:
\multiply\barline@depth -1\relax
\advance\barline@depth\altitude
\else
% Taktstrich unterbrechen -> am unteren Systemrand anfangen:
\barline@depth=0pt\relax
\fi
% Nein, nicht bei linienlosem System:
% \advance\barline@depth\hlthick
{\expandafter\ifx\csname h@bl\number\noinstrum@nt\endcsname 1%
% Taktstrich in der Zeile unterbrechen:
\y@v=0pt\relax
\fi
\raise\altitude\rlap{\vrule\@depth\barline@depth\@width#1\@height\y@v}}%
\barline@depth\altitude
\advance\barline@depth\y@v
\repeat
\addspace#1}
% Individuell getrennte Taktstriche einschalten:
\def\indivbarrules{%
\let\writ@rule\rul@indiv
% Taktstrich unter 1. System immer unterbrechen:
\sepbarrule 1}
% Taktstrich unter Instrument #1 unterbrechen:
\def\sepbarrule#1{\expandafter\let\csname s@bl#1\endcsname 1}
% Taktstrich unter Instrument #1 verbinden:
\def\conbarrule#1{%
% Taktstrich unter 1. System nie fortsetzen:
\if 1#1\else\expandafter\let\csname s@bl#1\endcsname\relax\fi}
% Taktstrich im Instrument #1 unterbrechen:

% Taktstrich im Instrument #1 zeigen:
\def\showbarrule#1{\expandafter\let\csname h@bl#1\endcsname\relax}
