Vertical space command which is between \intertext and \shortintertext

Question

Is there a way to define a command like \notsoshortintertext with two parameters to define the vertical space before and after it?

The problem I have is that \intertext is to wide on a specific page resulting in a poor page break. And with the \shorintertext I get an underfull vbox. So I would like to tune the vertical space at that point. I've tried to find the definition for \shortintertext, but wasn't able to understand the quite cryptic definition in the mathtools.dtx.

You could also consider using this technique: How can I add left aligned text to an equation? — Werner, Nov 30 '15 at 18:31

If no spacing is still too much, you can use negative spacing.

\documentclass{article}
\usepackage{mathtools}

\MHInternalSyntaxOn
\newcommand{\adjintertext}[3]% #1=above skip, #2=below skip, #3=text
{\ifvmode\else\\\@empty\fi
  \noalign{%
    %\penalty\postdisplaypenalty\vskip\belowdisplayskip
    \vskip-\lineskiplimit      % CCS
    \vskip\normallineskiplimit % CCS
    \vskip#1
     \vbox{\normalbaselines
       \ifdim
         \ifdim\@totalleftmargin=\z@
           \linewidth
         \else
           -\maxdimen
         \fi
       =\columnwidth
      \else \parshape\@ne \@totalleftmargin \linewidth
      \fi
      \noindent#3\par}%
    %\penalty\predisplaypenalty\vskip\abovedisplayskip%
    \vskip-\lineskiplimit      % CCS
    \vskip\normallineskiplimit % CCS
    \vskip#2
 }}%

\begin{document}
\begin{align}
x &= a\\
\adjintertext{0pt}{0pt}{no spacing}
y &= b\\
\adjintertext{\baselineskip}{\baselineskip}{big spacing}
z &= c
\end{align}
\end{document}
