Definitely.

If you want to give it a try...PA allows one readiness monitor to be incomplete and still pass inspection. The rear O2 is normally the last monitor/test to finish, as it requires a lot of cruising and multiple starts before it will throw the light.

You can reset the ECU, drive around with a scanner plugged in (following routines similar to the published drive cycles needed to complete each test)...and when you get all but the O2 test cleared, park it at your inspection place to have tested. Less of a PITA than swapping the DP (really that much harder an AWD vs. a RWD?)

Hopefully those guys on the E90 forums (Canadian I think?) getting close to a cheap fix come through....
