It's debatable.

What needs doing is for someone to take the most recent release of the Bitcoin Core client and merge in all the CLAM changes. But the Bitcoin Core code is big and complex, and it's easy to mess things up. I'm not sure how xploited used to do it, but it's quite a big job.

I believe the syncing issues are the same as the syncing issues we used to see in Bitcoin. They've been fixed in Bitcoin Core, so basing CLAM off a newer version of Bitcoin Core would almost certainly fix the problems. (And also give us all the efficiency improvements and new features that Core has these days to boot).
