More seriously, can you (Garrett) explain why certain design decisions were made with this concept?
Why is the metal so thin? Why use 6" wheels? Why not use two different diameter wheels to perhaps achieve some sort of speed difference between the two modes? What is the intended use for this module?

I know it's titled "concept", but these are all questions that need answering, as without answering them quantitatively, you're not really engineering, just doodling cool stuff in CAD (and if thats what you want to do, by all means do it). If this is a serious consideration for future use you have to understand the design decisions you make.
