There's nothing dimensionally that would prevent you from mounting a BP #2 on the AT-PL120. The PL-120's built-in phono stage can probably handle the Blue Point's lower output. You will find that you have to turn the volume up on your Parasound unit to achieve the same in-room loudness.
To get a better match with the BP #2, you should probably get the Sumiko headshell as well. It's a bit heavier and should raise the tonearm's effective mass to better match the compliance of the BP #2.
You may want to consider the Ortofon 2M Blue instead, however. It has much higher output and its compliance is almost certainly a better match for the PL-120's arm than the Blue Point.
The editor of the online Tone Audio magazine reviewed the AT PL-120 in Issue 11 on page 9. He liked a couple of Ortofons and a Grado wood-bodied Platinum. In private correspondence with another editor who was working closely with him, he told me they found the 2M Blue to be a surprisingly good match with both the PL-120 and the turntable that inspired it, the Technics SL12x0.
