Default [Q] is it possible to flash OPTIMUS 7 rom over Quantum?

Hi,

Is it possible to flash OPtimus 7 rom over Quantum ?

I need the WiFi tethering badly , no provider of Quantum has released it yet.?

Have anyone tried this ?

Or sending the ICS related .cab files of Optimus 7 to quantum will make it work.?

Please share your thoughts
