I believe you can select both drives in the installer and just tell it
to stripe over both of them.

Failing that, you can install to just one drive, and then once you've
got the system up and running, you can add the other drive as a second
vdev to extend your zpool.

Not sure about being able to break into a shell at an appropriate point
in the install sequence though -- I've never wanted to.  I think it's
possible.  Shouldn't be too time consuming to run a few experiments with
the install media though.

Personally I wouldn't run a zpool with striped hard drives as you are
proposing: if either of those drives fails then your entire zpool will
be destroyed.  However, it's at your own risk, and if you think it
acceptable, then go ahead.
