Here is a very cool plugin that has just been released (I have been involved in beta testing it).  A different solution that's a great alternative to drum replacement/augmentation: http://bozdigitallabs.com/product/sasquatch-kick-machine/
 
For more information & samples of what it can do, check this link: http://forum.recordingrev...amp;utm_source=fHumble fHingaz
 
Scroll down the page a bit past the silly video & you will see audio samples, as well as further tutorial videos on how to use it even further down on the right hand side of the page.
 
There is a trial version available if you want to test it out.
