Combine Wit's and Dervish?

That would put it on a price-point similar to Mercurial and finally solve the problem of Wit's not really fitting in anywhere (by removing it). It would give champs more interested in attack speed an alternative to Mercurial and it would also provide us with a big-ticket attack speed item, something the game is really missing out on right now.
So basically you would be looking at 75ish attack speed, some OnHit magic damage, magic resist, a MR stealing OnHit effect, and of course the Quicksilver active.

) as a component item with two upgrade paths.
Combine with
to create Dervish Blade. Gets Quicksilver, but lacks MR stealing.
Combine with
to create Madred's Bloodrazor. Lacks Quicksilver, but gains MR stealing and %Max HP damage.
