I had the same idea as you on my 54. I don't want to drop it all the way to the ground, but a slight drop would do.

I used a MII crossmember and added 1.25" of material to the lower crossmember and trimmed the same amount from the upper hats.

With a stock style MII setup, it is going to limit the total castor. The upper a arms will hit the frame if rotated all the way to the rear. Since I am stuck in build purgatory, I can't say if it's a really big problem or not. 1" of spacing would've been a whole lot better than 1.25.
