What conversion command? If you are using a "native" format, that is one
for which xetex has a library, no conversion is involved. Then xetex can
simply open it, get the size and continue with the page setting. 

Also \DeclareGraphicsRule isn't a command that requires something. It is
command that informs latex or xelatex or pdflatex how and if a certain
format can be handled.
