Can I use AA batteries with AAA batteries, 4 of each to get 12v to power a 12v motor that runs a fan?

You CAN, but it is not a good idea.
The smaller cells have higher internal resistance;
therefore the maximum current available will be whatever they will pass.
AAAs are really not suited for even a very small, very efficient fan.

yes but the AAA batteries will die sooner.

Yes, but the AAA runs out first much shorter than the AA.
