GRIP2 +Luftkappe or Fit4+Fractive+Luftkappe?

Wait what? How much do you weigh? Unless you're running about 120psi your rebound is way too slow and causing the packing problem
Start opening that up, then the first upgrade I suggest is the Luftkappe, then you may as well go for a fractive tune which is much cheaper than a new damper and will be properly tuned for you

I agree, I have never heard of someone running 1 click off from fully damped rebound...something odd is amiss...I def recommend figuring how to get the most out of current fork before moving into modification of the internals

Ok, that makes more sense now. Sorry if I missed your weight in the first post
Basically, the fork is way underdamped for you in compression and rebound so you will have to compromise ride quality somewhere by staying with the stock damper.
You could go with less pressure and faster rebound, then add in some volume reducers. That might improve sensitivity but it will be less stable and harsh on bigger bumps.
You are definitely a good candidate for the Fractive tune, although it doesn't include a rebound revalve as standard so I would request a firmer rebound setting at the same time.
I've fitted Fractive kits for several people 220-260lb, usually along with a luftkappe and had great feedback

Grip2 has noticeably less sticktion then the Fit4. It is the gold standard of dampers right now. I have cycle both of them out of the fork. Fractive tune will not be better than a stock grip2 as the lower seal on the fit4 contributors the majority of the drag.
I've had grip and grip2 and FIT4 with fractive tuning. The last option felt the best to me. Cycling dampers out of the fork is hardly the best test I wouldn't think.

Cycling the damper out of the fork will provide zero information on the actual damping. We agree on that.
It will tell you how much break away force is required to start movement though. That break away force is a major contributor to small bump compliance. It also changes the stick and release characteristic when braking or transitioning your weight.
The Grip2 lower seal has a loose fit and contributes almost no friction to the damper. It's pretty amazing how little force it takes to initiate travel.
With that said, Vorsprung is top notch! Everything they make is awesome and will improve your bike. I'm sure the the fractive tune is a big upgrade and will make a noticeable difference.
The fractive kit will work great for you...that’s why it has several options for compression tunes. Have a look at their youtune calculator to see what I mean
Not sure what they are talking about the bladder system not working for big guys.....that’s rubbish it doesn’t make any difference.
A rebound revalve is simple, I would suggest your man emails vorsprung for some guidance or else he can always email me as well

If your spring is sub optimal it doesn't matter what the damper is doing.
Sadly someone loves to bamboozle people and riders and sell them the latest old tech.

Your weight has no bearing of how the bladder of a damper works other than the extra heat created. Unless you are only using it for DH runs back to back heat will not be an issue. Open dampers are easier to service and cheaper to make, but weigh more and use sub-optimal fluids. Since it shares the open bath with the lower legs.
