One point I'll mention, as I recently modified a Norther Tool welding cabinet to accept two 150 CF bottles, which included ditching the single, loose-fit chain bracket that was well below the centerline of a 150 CF bottle.

So, maybe it's just a quibble, as two ratchet straps, even below the centerline will undoubtedly secure the bottle well enough, but if I were building a completely custom cart I'd probably have put a couple of uprights and a crossmember at the height of the top of your welder, to secure the bottle above its centerline.
With the lashing straps pulled tight the bottle is one with the cart. It might as well be welded in. I even shove it sideways by the bottle well above center. No worries
