First ?: Yes
Second ?: Using just one switch you will be putting 24 volts into the 2 fans. They would run ..but not for vary long.
Try using just one 8 AA Battery Holder....and see how the two fans run...being the start voltage is 9 the two should work fine as a prop. If you want them to spin faster add a 4 AA AA Battery Holder to bump it up to 18 volts. .....course a pair of 9 Volt Batteries would take up less space.

If you had a "DPST" switch (Dual Pole, Single Throw - which is essentially two switches with one toggle arm) you could still keep your two circuits isolated.

As noted above.. using 1 - 8 x AA pack would be enough (since really current is your limiting factor here, and the AA pack should have enough to run both for a little while just fine)
If you wanted longer run times and keeping with your 2 - individual 8 x AA packs.. then use a DPST type switch as mentioned.
I'm not clear if adding more voltage (over the mentioned rated value will blow the fans or not?)
* I would stay away from using any 9v batteries.. they are notorious for being crap and have little current.

Yeah forgot about that xl97... 9V tend to juice out rather quickly....do to how they are made.
