The UAD-1 1176LN compressor has quite a bit of an edge, you just gotta abuse it a little
Also, I find that the EX1 compressor can be pretty brutal.
Come to think of it the compressor that's part of Nigel also has an attitude, although it's not as tweakable.
I wouldn't bother with the UAD-1 reverbs though. In fact DreamVerb is one of the worst I've ever seen.
BTW not all hardware is "warm". AKAI samplers for example wouldn't be considered "warm". When I think of my Kurzweil K2600 the word "warm" doesn't really enter my mind. Clean, accurate, faithful, oftentimes quite wonderfully digital (specially when you do things to exacerbate the aliasing artifacts) and terrorisingly ugly, but not necessarily "warm". You gotta work for that. I think that word has been thrown around so much that it really has lost its meaning.
Concerning the Rumour/Mangler... those units are based on the K2600 KDFX processor... they are absolutely wonderful! Mangler has some rather interesting FX that you can't find elsewhere, and the Rumour reverbs are definitely great for creating spaces. From lush caves to just rooms. If you're interested, I can perhaps post some examples put through some factory KDFX presets that coinside with the ones in either the Rumour and/or Mangler.
