The cameras were bolted to the spacecraft in that orientation probably about two years ago - and now lay smashed on the lunar surface.
I'm going to say yes...it's a bit too late. |

Here's an updated version of my Nearside Moon map with the GRAIL impacts added.

Yes it is - no more farside impacts. Incidentally, Chandrayaan-1 was predicted to impact in 2012 as its orbit evolved, but as it was not tracked or trackable we don't know where it fell.

LROC spots craters formed by GRAIL probes (sorry I couldn't find the original paper in the conference abstracts):

Wow. LROC is an impressive instrument indeed, and their science team is getting very good at this sort of thing. Well done!!!

There is no abstract, this was a press conference, not a paper. It's cool to see this even with LRO in its higher orbit.

How accurate were the pre-impact predictions?
Here is an overlay of the pre-impact prediction on the new topo map showing the actual impact crater locations. B was nearly 1000 m off its prediction, A only about 600 m. Not bad! Phil
