yes, it is possible, but not the suggested way to do things ...

you can either give the guest the necessary permissions to
the guest (in form of capabilities), which will allow it
to mess with networking in general, not just that interface

or you can use network namespaces (present in recent kernels)
and set that up with a virtual ethernet interface and a bridge
on the host (more overhead)

but in general requesting a second dhcp id on the host and
assigning that to the guest is much simpler and a lot cleaner :)
