Must say I like this thread. Got 3 x V6' and the '90s V4 along with 4 x 1248 cabs. Use a T-bass. One of the early ones.

I have tried out several ways to stack the rig. A couple options you can se on the pix I uploaded.
Here you can see the V4 in the bottom, then 3 x V6 and finally 2 x 5001. Also have 2 x GK Fusion 550 there. At the moment it is them I use.
Sounds great as well.
A couple of I swopped the 1248 upper left, with one like the three others. So now it not only sounds great !! It looks great as well.

Only thing missing is a V8. :-(
