I don't see why you couldn't have a mud bed and a wet/dry you would just need a sump for your wet/dry and a refugium (spelling?) for your mud bed. Just means that you would need a bit more space under your tank to store all that.
Rutrag said:ne alternative I have seen (and cannot speak to its effectiveness) is to run chamber with some kind of media with low waterflow off the sump. The theory is that the water becomes anaerobic and the media provides a surface for the anaerobic bacteria. Others use live rock where the theory is that water permeates to the middle of the rock at a slow rate, and it's anaerobic by the time it reaches the core.
That's pretty much what's in my mind now... Have the sump set up with a decent wet/dry stack at one end, return pump and other such equipment in the middle chamber and a refugium in the end chamber with a high wall holding back a deep bed...
Perhaps overkill for the sub 10g tank I have currently but certainly some nice ideas for future set up!
