Slimline build suggestions

[wyoung]

I'm building a thinline flattop for a customer, and I would like your input. I've never constructed an acoustic with such a shallow body, and the customer, too, wants to make sure that his guitar is low on volume but full on tone.

Here are my considerations:

Use a medium density wood like walnut.
Make a larger soundhole.
Heighten the bracing under the top, as well as back.
Glued-on bridge.

I want to hear from others who have tackled such a project and their results.
