Yes, subject to the following considerations:
Each driver should register separately on motorsportreg.com, using a different number.
Whichever driver brings the vehicle to grid will stage in the two-driver line, as directed by the grid worker.  As an aid to the grid worker, it is helpful for the driver to hold up two fingers to indicate that they are in a two-driver vehicle.
It is the responsibility of both drivers to ensure that the correct numbers are displayed on the car for whomever is driving for a particular run.
When the heat begins, all of the two-driver vehicles will take one run with one of the two drivers.  Then, half of the single-driver vehicles will take their runs.  At this point, the two-driver  vehicles will run again with the second driver, followed by the remainder of the single-driver vehicles.  This process repeats until all timed runs have been completed.
It is at the discretion of the drivers whether they want to alternate for each run, one driver take all of their runs before switching drivers, or any variation thereof.
