I'd like to be your tailor...
Good luck. FWIW I think those wider stripes from Lesser work very well. I used Smiths 8860 I think and that's worked out very well.
Will be interested in seeing how it all pans out so do post photos at the end please.
Allow me to recommend a shirt like one of the white collared ones here http://www.styleforum.net/t/405608/hong-kong-shirt-makers/30#post_7740702
