Starting the AP with Part 3?!

[Dryder]

I need some advice from someone who has already DMed the AP. 
Beware - SPOILERS for CC and the Carion Hill-Module!!!

The background… (spoilered, to keep the post clean):

Spoiler:

… I started a group of players new to PF last year, and they wanted to try it first. So I decided to DM the Falcon Hollow series. But after two sessions, they totally jumped on the system and the world and wanted for more! Now they have such cool backgroundstories for their pcs, that I just don’t want to start with new pcs, and an AP.

The group is level 5 and has played through the following modules:
- Falcon Hollows Last Hope
- Crown of the Kobold King
- Some sneaking around in Kreeds manor to free Ulizmilla… :)
- they are now in the middle of Return of the Kobold King.

So I wonder how to proceed from here on. I wanted to get them into the Carrion Crown AP somehow, starting with Broken Moon, because it somehow fits to the Drazmorg story. So I have the following sequence in mind:

- Hungry are the Dead: adjusted to Level 5
Drazmorg found the seal and the Ectoplasma, which Adivion needs, below the monastery featured in Crown of the Kobold King. The group will encounter Adivion in Falcon Hollow, while he’s visiting to get the Ectoplasma first hand from Drazmorg.

- Carrion Hill: adjusted to Level 6
The PCs get invited by judge Daramid, who is a friend of the father of one of the PCs (who’s also a member of the Paladine Eye). Daramid explains what happened “during the first two parts of the AP”, and that they fear that someone is trying to get all the incredients for the crown. The release of the Shogotth is only a diversion to be able to steal the seasage effigy, which was hidden somewhere below Carrion Hill.
Judge Daramid functions as a tool to inform the PCs of whatever they need to know to be able to start the AP with part 3.

One of the PCs is desperately searching infos about her past (and future), which she might find in the library of the Ascanor Lodge…

My questions:
- Do I have to take care of something else?
- Would Drazmorg work as well as the BBEG of the AP, if I manage to let him survive?
- Any idea what would cause me troubles with all of that?

Thanx already for reading this lengthy post!

I really like the first two parts of the adventure path. It is my opinion that you should run it as a whole at a later point in time, so you all get the full experience. Carrion Crown is a very different kind of campaign than your typical pathfinder game, so jumping in, in the middle, sounds problematic to me.
