Standard mistake.  When redefining hook token registers, you need
_two_ extra control sequences, not one.  Something like

\let\my@@output\output
\newtoks\output
\let\my@output\output
\output\expandafter{\the\my@@output}

\my@@output{whatever stuff I want and need
  \the\my@output for recursing to the original}

If you use \the\output for recursing instead of \the\my@output, then
multiple packages doing the same trick will conflict, and not properly
daisy-chain.
