The bat is going to sound different than your pass, and maybe that's what you're after. somewhat warmer, richer, very vibrant mids w/ highes and lows a little softer. The 75SE is a much better on the extremes, but doubles the price. Excellent staging and depth for any of the bat amps.
VK60's are pretty easy to sell, you can very likely buy one, try it, and resell it with only loosing the cost of shipping. (which at 70lbs) is 60-$100.
You're cutting your power quite a bit, for the b&w's. Depends on how big the room and how loud you listen if it's ok...I have had a single vk60 driving wp 6's and it was plenty fine.
