So, why build your own? That sounds like a pretty cut and dry use of COTS components? For example
http://www.wcproducts.net/wcp-shifter-3cim/ (scroll down to the charts for the speeds) has several options that meet your needs.
I'm not saying don't go custom, just saying that you might want to look at options and see what concepts you can steal.
