Why not?  I see no reason the SPI cannot handle 2 bytes consecutivly.
The first 8 bits fill the shift register, get transfered to the SSPBUF,
sets BF flag,
and continue filling the Shift register.  You will HAVE to move the byte
out of
SSPBUF before the shift register fills!  (Collision)

Mind you, I've not tried this, but I see no contradiction in the manual.
