Many builds of iPXE (e.g. bin/ipxe.pxe) will support multiple drivers. 
You would need to create a per-netdevice copy of the vlan_operations 
structure, and modify this instead.  You would then need to modify the 
various "is this a VLAN device" tests, which currently compare 
netdev->op to &vlan_operations.  It may be simpler to think of a 
different test to be used in netdev_irq_supported(), so as to avoid the 
need to modify the way that vlan_operations is used.
