Hi Poboy,
You've really put a lot of thought into what you want. What you describe is certainly attainable if your wife enjoys the role your asking her to take.
You both may want to check out Mistress Akasha's web site. While there are a number of member only articles, there is a great preview of "The Good Girl’s Guide to Domination" locate here:

Print and review it together. Is this something that you both are seeking?
To your success!
Ruby
