I'd love to help out if I can. I know a bit about Photoshop and ADW.
You want a simplistic look, can you explain a bit more? I'm not familiar with "blur's simplistic white outlines" but doesn't sound too hard to replicate if I have something to go by.
As far as ADW goes, you can replace the app drawer button easy enough. ADW has option to change size of icons in dock by slider from below default on up to full size icons like homescreen icons.
Not sure if this is part of what you were trying to accomplish or not, but... you can use both action buttons (either side of app drawer) and both secondary action buttons (outside icons), OR you can use either/or to have only one pair in use. The point being that if you only want 3 icons, you can have 3 in the middle or use the ones on the end, skipping one on either side of the app drawer.
I haven't tried making an ADW theme, so I don't know what all that encompasses, but I do know ADW has option to make dock icons look like the LP icons, no color and sort of transparent like etched glass. I've seen ADW themes that change that to a solid color.
