You cannot use the wideband to replace the stock o2 and send the signal back to the ecu.... It wont work...

You CAN use a wideband that has an o2 output and get both a gauge reading from the wideband and send a simulated signal back to the ecu...

Best option here, would be to have a second bung welded into place, and use the wideband at least 16" after the turbo....
