Currently, I have 2 .com urls set up with multisite pointing to 2 different templates.

Is it advisable to created multiple "config_sites files" to point 2 other .net urls to the same 2 templates.

eg.
www.mysite1.com and www.musite1.net pointing to template1
and www.mysite2.com and www.mysite2.net pointing to template2

any help is appreciated.
