Oh, of course. Yes, then it's probably only somewhat
more expensive, on average, to build two 90-turners than to build an "almost edge-shooting" 180-turner that leaves let's say one block past the edge of the shooting range. The nice thing about an almost edge-shooter would be that there are so many lanes available to shoot down a block, and it can be done any time it's convenient during the conversion of the ash to the new target.
So an almost-edge-shooter 180-turner will cost one turner recipe plus maybe two or three gliders to get a convenient extra 90-degree output -- whereas two 90-turners will cost two full turner recipes. Turners so far seem like they'll come out to maybe 8-12 gliders, including rebuilding a (-3,-6) target (?) So we could save half a dozen gliders.
But... argh! I shouldn't be measuring in gliders! The two 90-degree turners can be built with two parallel recipes, so the cost will be just one turner recipe. That might come out to... what, five to seven resets, maybe? Getting the target to move leftward and away to (-3,-6) will be the hard part, I would think.
The thing to conserve will be the width of the monochromatic recipe -- the more parallel recipes we can fit into a single 39fd (or more or less) shooting range, the faster the whole construction will get done. Maybe to do seven parallel recipes, it will be worth setting up a double-width shooting range, about 80fd. Or maybe we can get away with a 40fd range that wanders back and forth a little. We can figure all that out once we know what recipes we need to build.
Anyway, I guess it still looks to me as if almost-edge-shooters might be competitive, if they exist -- they'll likely be a little narrower than recipes for two separate 90-turners.
I wonder if it will make sense to point multiple elbows at the superslow elbow in the NW, to get that work done faster? Maybe when a 180-turner's construction is done, its glider lanes could start being used to increase the speed of the NW construction. All that's necessary is to leave an extra target just beyond the edge of the 180-turner's range, lined up with the NW superslow elbow.

To my knowledge nobody has ever attempted to collect cheap recipes, either mono- or polychromatic ones, for 90-degree turners where the input comes from a different direction than the construction salvo (as in the case of this proposed SE->SW turner.)
