1. Wow, so it sounds like you literally can remove it from your device via unscrewing, pull the top cap off, reach in with your fingers and just unscrew the CE2 from the base and pull out, take the new CE2 and screw in from the top into the base, refill from the top, recap and finally screw onto the battery.
Ok, how can I give you monies for one

.
I just started messing with the CE2 and with some messing around was able to get it wicking and all that pretty well (just cut notches in the top cap that covers the top of the center pole and shaved a 'tiny' amount of the plastic from the bottom of the same cap.
Im trying to figure out where the heating element is as I think I might be able to completely remove the top cap and just push the O ring (the one that sits above the top cap) down until it sits flush with the top of the center pole.
Then to refill the CE2, I can just use a pen to pop the O ring out and carefully drip down the side (being careful to not get it into the center pole if I am understanding this thing correctly).
2. I hope I am understanding this correctly, the center post shouldnt get flooded (maybe a drop or two of liquid is ok).
2a. As a little side note, whats the usage life like on these CE2's? Im thinking maybe a week or two?
3. Where is the heating element in these CE2s? Is it at the top of the center post or the bottom near the 510 threaded connector (I 'briefly' looked at it and then after I filled it, I started thinking about how to modify these to be useable without a syringe while I wait). If its at the bottom, Im curious as to how the wicks get liquid down to the bottom as they seem to just be stretched across the top of the center post...
I think the flaw with these CE2s is they have them designed backwards. If you could remove the 510 threading from the bottom via screw threads and then fill it from the bottom, these would work well.
The design change would simply require a metallic bottom base around the inner part of the plastic tube with threading both along the center post and reverse threading around the outside bottom portion of the tube with maybe an O ring.
Anyway, Im thinking to hard about this but I am almost positive I could come up with a way for these things to be easily refilliable and to wick correctly. I dont understand the designers of the CE2...
K, off to drink some more, Im rambling now...
