Yep, as said, Trilogies or Slowhands will get you where you want to go.
Slowhands have a fat mid and plenty of low end, but retain the traditional stratty top end you expect to hear from a single coil.
Moving up to the Trilogies, the treble response smoothes out noticeably, though I would say the low mids aren't as fat as with the Slowhands. The Trilogy bridge is close to a P90 in sound - very fat and powerful but still easily distinguishable from a humbucker.
Personally I'd recommend Slowhands as your first port of call since they are more dynamically responsive. For some extra power in the bridge position you might want to do as gwEm has done and opt for the zinc-plated steel baseplate.
I hear the Trilogy Suites are not suited well for the Yngwie tone, and are totally different beasts.
I wouldn't say that at all. What is different is the approach to achieving that tone. Yngwie's pickups are generally very traditionally stratty in sound, and he relies on his smooth technique to achieve the fluid lead sound he's renowned for. The Trilogies are voiced so that a player can get a similar sound through their own rig with minimal change to technique.
Similar deal with the Irish Tours for example - Rory and SRV both used stock strat pickups but got their tones through a combination of massive strings and brutally heavy right hand technique. The Irish Tour set gives you a slice of that big sound by means of their extra output and gritty voicing, so you can use more comfortable string gauges and not have to go all UFC on your guitar every time you play :lol:
