Hi Wes,
I checked with my cousin Riley Doty, a veteran tile contractor/setter, who
thinks what you're planning sounds fine. His only warning is that the
stuff has an uncanny ability to find and travel through any little holes or
crevices, so make sure there's nowhere for it to leak out.
He also added that the self-leveling cement reps would say there's no point
in adding the backerboard, but he thinks it's a good idea. He's seen some
slight tendency for it to fracture over time in some circumstances, so your
backerboard resolves that issue.
Feel free to check with me if you have any more questions about it.

Wes-
Sounds like a good plan and an additional consideration could make it
better. Wood expansion/contraction under tile will be a problem that is
minimized with slits through the plywood using a skill saw. They can be
10 - 12" long and staggered with 3 - 4 " seperations. Lay tar paper
(overlapped) over the wood before the leveling cement goes down.

Dear Wes,
The only thing I would add is to tape the joints between the backerboard -
using the mesh tape used for drywall work. I tiled m bathroom in my house
which was an older house. The slope was certainly greater than yours and it
was across 5'. I didn't level it and after it was tiled you really couldn't
see the variation.
