Batch sparging is not as equipment dependant. All that really matters is the grain is well mixed w/ the proper temp sparge water and drained. With fly sparging, manifold dimensions are critical to achieve a thorough rinsing of the grains without channelling. This is why most fly spargers will use a false bottom or a manifold that covers the entire bottom of the tun. With your basic set up, there is a good chance that the sparge water will find a "short cut" to the braid and not rinse the entire grain bed. W/ batch sparging you mix the grains and sparge in batches and drain the entire tun and rinse the grain in "batches" rather than a continous rinse w/ fly sparging.
I see no reason why one couldn't siphon out of the mash tun w/ a proper set up. You do want the braid to lay flat on the bottom to completely drain. Your sketch shows the braid bent at a 90 and I fear it might kink and limit flow.
