overthinking single tier

I currently have 3 bayou classic burners on stands and 2 chugger pumps (one was just gifted to me).  I recently bought a welder with the plan to build me a rig, but now I'm out of beer and I have yet to build said stand.  I am thinking of "temporarily" putting my 3 burners on a flat cart (or on the floor for that matter) and connecting my pumps to brew.  I saw that Austin Homebrew sold 3 burners and called it a 3 burner system.  then I saw this brewbuilt https://www.amazon.com/BrewBuilt-AfterBurner-Deluxe-3-Burner-Brewing/dp/B01AK7GMS6 and thought, "I could go outside and bolt my 3 burners together and add wheels to one end for less than $20 bucks. 

I keep thinking that I am overthinking the brew stand and maybe just want something shiny and neato. Am I missing something or (wheels cranking) can I just go bolt/weld my burners together, slap em on a flat cart, connect my pumps and have a brew cart that will make beer just like a $1000 stainless cart?  tips? guidance? insight? inspiration?  anybody?
