For me that was a gut feel number. I don't know what the minimum (that will work) number is. I hope you can resolve it.
I'm doing a little of what Scouting Dad suggested checking with a level, shimming... It looks like I can get away with less than 2 feet. I think to make it work, I will have to leave the switch farther to the right of the original plan, and have the siding end on the lift up. That's no big deal at all.
