What's the census here?
It can be done and would be around the same stregth with DOM being a little stronger (1.5"x.25" wall) from what I gathered. I know DOM is about 11 a foot where solid i want to say is 4 from when I was researching this.
Could consider 2x2x1/4" as an option. With the solid you are going to have to run a threaded joint on both ends. and If you use a threaded poly joint at one end and a johnny joint at the other you are looking at about 80+ bucks for joints for a lower control arm.
