I would say an Emi Swamp Thang would work well. I have an 8 ohm that I had every intention of putting in my Blues Jr., but I tried it with an 8 ohm EV 12L in my PC 2x12 and they sound so good together, I guess I'll just have to pick up another at some point to put in the Blues Jr.
I'd say since you have all three, try them all out to see what you like best. After all, no one knows your tastes like you do. If possible, make some clips with each one so you can listen to them back to back.
