I actually made a blog entry regarding hybrids not so long ago, you can find it here. But for in case you don't want to read it and the comments, I'll put it straight: The actual consensus is that there are not enough hybrid items, not even one focused for late game. Should there be such items, there should be more items designed to counter mixed damage, like Guardian angel or Aegis of the legion, but more focused into countering hybrids. That said, there are little to no characters that benefit from hybrid build more than focusing either on AD (Or AS in some cases, instead of AD) or AP. They are even listed here.

However, if you do find a good hybrid build for characters like Ezreal or Tristana, please, let me know about it, I've been searching for it for a long time, without satisfactory result. My best attempt was going Berserker's (When, although it may seem good, Merc's tend to be a better option since carries are the first ones to be focused and CC'd in teamfights), Malady, Black cleaver, Hextech gunblade, Infinity edge and Rabadon's deathcap. As I was adviced, it sounded good, because although the AD and AP stats would be low, Malady+Cleaver would shred mres and armor enough to deal a good chunk of damage, while keeping a good ASPD... But again, as I was adviced, with little to no item synergy, this build actually did not work on them in a viable way. Why building Rabadon's when you already have Infinity to lean more on AD? When to upgrade Vamp scepter into Gunblade? Also, if you've already purchased Infinity, you will be greatly tempted into building a Bloodthirster instead of the Gunblade. Given the fact that they had the advantage of range, I don't actually think that going AD+AP could work on melee characters like Trynd, at least not better than going full AD carry.

Hope I've helped.
