Welcome to the Integrated Assessment Modelling community. This seems to be a serious attempt to grapple with the issue and produces mean SCCO2 values much more in line with recent PAGE09 analyses than other efforts.
I would challenge your assertion that 'Past estimates of the SCC have included limited uncertainty analysis focused mostly on a limited set of parameters such as the social discount rate'. This is clearly not universally true.
See, for instance, 'Critical issues for the calculation of the social cost of CO2: why the estimates from PAGE09 are higher than those from PAGE2002', Climatic Change, April 2013, Volume 117, Issue 3, pp 531–543 https://link.springer.com/article/10.1007/s10584-012-0633-z#citeas particularly figure 3 and the subsequent text, which shows the eight major influences on the SCCO2 in the PAGE09 default model. Overall, the PAGE09 model uses probability distributions for over 100 of the most important inputs, and calculates SCCO2 values from 100,000 runs of the model.
