Yeah, it might be a tight fit, but I see a spot where a plumber can snake around the pipes to fit in a SWCG right before the valve right side of the chlorine puck dispenser. It won't be pretty, but plumbers get creative with PVC pipes.. LOL... But I gotta say, your equipment pad seems quite dense, especially the two pumps are quite close to one another. It might be little challenging to clean out the basket in the water feature pump. Luckily, you won't have to clean out water feature pump basket often. My pad was initially about that size (6ft long). I demanded my PB to extend it another 3-4 feet.
