Any reflection off the wood would be minimal, especially with thinner frames. 2" of 703 absorbs mid and high freqs darn well...supposedly better than brand name foam products.
Besides that, I think a wood reflection sounds a bit more 'natural' as opposed to 5/8" sheet rock, or brick.
Having more 703/705 would allow a deeper range of frequency absorption, but still, even this is minimal.
A few others here will tell you that besides a few inches of 703/705, an equally important concept is to have an air space behind the trap, which allows for the optiminum absorption from the panel. The space can be adjusted so that trouble freqs are attentuated to your liking or preference.
