hmm. 
I can't see that [yes, odd, reset] implements the conditional I need to override page[odd]. (see code comments below)
but I guess the real problem occurs because I have to inject this in  \everyafteroutput.


\newtoks \EvenPage

\appendtoks
\the\EvenPage
\global\EvenPage\emptytoks
\page[odd]   % will be overridden by page[disable] 
\to\everyafteroutput

\unexpanded\def\Figure#1{%
\appendtoks
\page[even]
#1
\page
\page[disable] %disable the next \page[odd] because else it will insert
\to\EvenPage}
