Ways to lay this cyrstal out without increasing the PCB footprint?
Your layout looks almost perfect already. If you had place, you could place everything a little bit better, but the influence is so tiny, you will never spot the difference. 

Remember, you can built this circuit with THT components on a breadboard and it still works. 16 MHz is not really a lot on a PCB. Trace lengths and length matching are not that important at these frequencies. In any case, make sure that the ground connection is good all around the crystal.

What I would do:


move the component right above the crystal to the right
move one capacitor in the now free space, leave the other where it is.
