Coldn't you get away with the high output version of the Dynavector 20X? It has as high an output as most mm carts. That is a pretty good cart and very musical. I might suggest you consider upgrading the cart on your Scout to the next step up in the Dynavector line. Especially if you are thinking of playing the better recordings on it. It is startling how much clarity and detail the 17D cart reveals compared to the 20XL or 20XH.
By the way this is a great idea you have to just have 2 setups. I've thought this was ideal myself but I don't have enough room to deal with it.
Oh and though I have never heard the VPI scout I can attest to the musicality of Nottingham tables. My first table was a Nottingham Horizon with a Dynavector 10x5 on it. I paid 800 used here on Audiogon. I was shocked by how much more I enjoyed the sound than CDs. I've been a convert ever since, though of course I still listen to and highly enjoy digital too.
