The answer is, I think, equally no and yes. 

Standard Stata commands should be fed at most one kind of weight. 
Either the command doesn't take weights, or weights are allowed, 
but at most one of the four kinds in one command. 

That doesn't stop you doing your upstream 
calculations and calculating composite weights
which then are fed to some other command. Typically 
this will be a multiplication, possibly followed
by a scaling. But you must declare them as one of a, f, i or p.
