You can, but you would also have to send each XSD file that's imported.  The
way I coded the wsdl generation is that each type gets its own XSD file. 

I'm sure there are tools that would easily traverse and save each file...
it was just quicker for me to expose the WSDL URLs using my firewall. 

(It will be a good volume/load test on my dev backend also!)
