MK1, my set-up is exactly the way you have stated. I also have a small blanket inside the bass drum on the bottom to help with some reverberation and possible overlaping of the sound to the next beat.
The further back you place the mic in the drum the more low end should be present. The closer you are to the drum and beater, the less bass drum you should hear, to a point.
I was going to try out having a mic set up on the beater outside the drum and one inside the drum as you have stated.
Kicking the mic on an angle helps reduce the direct sound pressure head on to the mic and provides added depth and body that you want to amplify with the mic.
Just my thoughts.
