RQM sync artifacts with HP QC

Hi, 

Is there any approach or strategy to build a custom extension to mirrow test cases/test plan with their corresponding in HP QC. 

We have seen there are pre/post conditions in RQM operations but as far as I have been reading there is no way to create new ones. We were thinking about synchronize RQM artifacts on save operation with HP QC. 

Another approach we have considered is the ability to explore from a WI save pre/post conditions all its linked test cases/test plans but we don't know whether the full test case/test plan specification can be read from a workitem link. 

Any idea on how to do it or do you think it is too risky to implement something like this? 

We know about tasktop adapter but those are for workitem and we are trying to sync test artifacts. 

Thanks
