would this be expected to have a (temporary) detectable impact on atmospheric carbon concentration (ie ppm)?

Yes, in a slight slowing of the rate at which it is increasing.

Hard to attribute with confidence since it's a global figure based on pooled local measurements, but so long as you agree that human-caused release of co2 contributes to increasing atmospheric co2 levels, the reduction is a safe assumption.

The depressing part is the reduction needs to be 10x greater, and permanent, and global, for atmospheric co2 to halt it's increase and start dropping.

Certainly not an obvious impact, at least not yet, according to this graph: https://www.esrl.noaa.gov/gmd/ccgg/trends/
