Sissy shifting is what it used to be called.

Shimano would say it is a no go, what you need to measure is the distance between the ring centerlines, if the same happy. Do note that Shimano and Sugino may not use the same thickness of chainring material, so measuring the distance between the rings may not be a good guide.

If good, bench test and field test, on the early SIS shifter, the factory jump was 53/39, if greater than that, might be a problem, it 50t or under for the outer ring, may not work. Don't sell your old crank until the new works.
