If I'm understanding you correctly, you have one burner that I assume you use to heat your strike water and to boil with. If this is the case, all you really need is a table that puts the valve of your MLT higher than the top of your BK when it is sitting on your burner. You can just pour your strike and sparge water into your MLT assuming you batch sparge. People who fly sparge using gravity instead of a pump will often use a small shelving unit. The sparge water tank goes on the top shelf. The MLT goes in the middle, and the BK and burner go on the ground.
