Colmap to VSfM to Colmap

Hi,
I am very keen to exploit VSfM georeferencing functionality but am very disappointed in its ability to generate good quality sparse and dense clouds. Colmap is fantastic together with Regard3D. Is there any way I can produce a sparse cloud in Colmap/Regard3D and import into VSfM to georeference and then export back out to finish? I realise I could scale the model after the dense Reconstruction, but this is not ideal.
Many thnaks
