Vandersteen 2ce tweeter swap?

Has anyone had good performance from a replacement tweeter in there 2ce Vandys? if so what have you tried? Thanks for your thoughts
Why would you not buy an exact replacement from RV? Entire speaker and crossover is an integrated system. Swapping out parts is HIGHLY unlikely to have a positive impact, unless you were talking about internal wiring, binding posts or MAYBE replacing passive parts in X-over with same value but better grade .
