The proposal by Fabrice looks better to me

-net usernet,macaddr=00:11:a:0:2:19 -net tunfd=10,macaddr=00:11:a:0:1:19

this way the syntax can easily be extended with new options as needed, and 
the exact order of things is not important (you just specify the net 
parameters as needed).

Only objection is that for the tunfd case I would use

  -net tap,fd=10,macaddr=...

What about this:

   -net tap,ifname=qemu0,macaddr=...
