You're the one that has to sell it and if you think that retail and service industries have lots of overlap, then absolutely you should talk about it. The more compellingly you can explain your case the better! It sounds like you really understand the limitations in your industry given your current degrees, and I would explicitly talk about how an MBA can skyrocket you into the positions you really are striving for. Your "insider knowledge" will give you a lot of credibility.
I can't say for sure that it will hurt you (for sure, it's impressive that you are working full-time AND getting a masters degree), but you just need to make sure to indicate how everything is working in concert to help you achieve your goals. It's just a matter of putting it all together.
I hope someone else weighs in because I like your story and think you have a great shot, but the flurry of Masters is a bit out there for my taste.
Blogging about the MBA application process. Because I need to do something with all this bschool energy.
