Personally, I think that I'd go the other way here:
The soft top end of the original Vandy 2 was an essential part of that speaker's character (and charm). I say "Don't fight it".
I first heard the Vandy 2 paired with the original Quicksilver mono amps (30+ years ago!) and loved the pairing for mid-range centric music. I specifically recall a demo of a lovely acoustic guitar recording that highlighted this effect.

PS The Johnny R who posted above is Audioconnection in Verona, NJ. It's the same store at which I heard the Vandy/Quicksilver demo, cited above (tho, at that time, it was owned by a different fellow, named IIRC Hart Hutschens).
