Some great work, I love that sort of "work it out as you go along" pragmatic approach to problem solving.
It always strikes me as funny when newbies ask questions about can some of these methods be used... the answer is yes of course, IF you know what you are doing and have the skills, experience and imagination to pull it off.
This post shows all those things ... great
I've done a few weird patches and repairs, but your project is way ahead... love it
