That sounds like what I was planning to do, those factory switches don't last long. I plan on replacing the high speed relay also so all three relays will be interchangeable.
I haven't seen any aftermarket setup, doubt there is one, but it should be simple enough to wire up from scratch. The hardest part will be bringing in a new power wire for the whole setup. It will be pretty easy for me , I put a few extra fusible links on my new power distribution block when I rewired the engine compartment.
