Currently, no (as I expect you discovered, if you tried); xetex uses 
the exact same code as other *tex programs to examine the first line of 
the file, and that routine looks only for a format file name and 
optionally a -translate-file option (which xetex won't use anyway).

However, I can see that allowing other options to be specified that way 
could be useful; I'll keep it in mind. On looking at the code, I notice 
that even the %&formatname option is only going to work if it's a UTF8 
file, not UTF16; I should fix that too.
