No, underexposing by 2 stops and pushing in post will make a visibily worse quality image.



The main reason for this is that you have now lessened the (already low) dynamic range of your image. This will be very noticable in the shadow areas of your image which I am guessing there are going to be a lot of since you are running at f/1.8 and querying about high ISO.



There will also be a lot more shadow noise/banding in the underexposed shot as digital cameras introduce a lot more noise in the darker areas than light.



I would be interested in seeing the test described above by Rainer (with no Noise Reduction) which I expect would back up my 2 reasons above.
