And I said you will have to use bytecode manipulation for this in case 
of other libraries (i.e. ones which you do not control or have access to 
sources to).

In a way, yes.  I'd rather say it's a matter of goals which one wants to 
achieve.  There are means which work well for some ends and not so well 
for others.  If the goal is clear solutions can often be pretty easy 
aligned according to "good" and "not good".

*What* content?  Why do you not answer this question?  You didn't even 
state that you do not want to answer the question (which I could 
understand if you do not want to leak out ideas you are working on). 
But coming here and asking while at the same time ignoring those who are 
willing to help to find a good solution is not a strategy to success.
