First off, welcome to the line and did not see a question in there nor do I see a problem with your plans. They are on the high end and see no reason to second guess you or provide any suggestions. You will probably find that if you decide to sell, you will not get your money back but heck, you can always tear it down. I have built up a few and now gladly settled with one. ....
Do us a favor and send up some pictures on your finished products. ....
Be Safe !!!
