No. Every model that has ever simulated solar dimming shows that the poles would cool relative to not dimming the sun. But, if you just turn the sun down then you “undercool” the poles. The plot is G1 relative to pre-industrial, not G1 relative to 4xCO2.
(These are the exact same model simulations that you’ve asked the exact same question about before.)
