As i stated in another thread, i think basically, every person can do every nen ability per se likewise to how every person could potentially imitate the movements of another person.
The reason why this practically wont happen is due to different bodies, mental states and thought patterns.
Every person has a certain flow, the way you move, the way you think, which will all shape his nen flow.
To maintain an ability, you need a lot of control over your body and mind, simliar to meditation (after all, even developing nen is hard).
The more complex your personality, thought patterns and so in is, the harder it is to imitate your ability.
For example, an enhancer's nen ability like gon's jankenrock should be easily imitateable.
It has not much to do with his personal experiences and gon is a fairly simple minded person.
Ging could definitely reproduce it is he feels the nen flow of gon and does not trying out.
One mode harder is an ability with a limitation.
I would think that ging could reproduce franklin's ability (maybe a bit weaker) even without cutting his fingers if he is good enough to bring himself into the state of mind of 'my fingers are pistols' because he saw that franklin has cut his finger tips off.
Then there are abilities like netero's or kurapica's which were dveleoped due to very personal experience which ging cannot simply reproduce (netero's training from hell, kurapica's scarlet eyes, backstory, and his rigourus training with the chain).
Reproducing nen is in my opinion as hard as completely imitating another person. It is easier with a simple minded person whic has fairly standard behaviour and thought patterns, but it is still incredibly hard because you need a very profound understanding of nen flow and of people.
Ging seems to be the only character who has that to this extent, but i think another person could do that to if he or she had the same understanding as ging has.
Now, chrollo on the other hand has a hatsu which enable him to delve into the soul and understand the nen flow of a person he steals from.
Chrollo could even copy abilities like netero's or even kurapica's while ging could never reproduce chrollo's ability.
