LiDAR with photogrammetry

Does anyone know if it is possible to set a spatial framework for LiDAR to be used for reconstruction while having a different spatial framework using just the photos for photogrammetry?

Can this be done all in the same reconstruction or do two different reconstructions need to be done and then somehow merged together? How does one go about merging two 3MX files or productions together?

I would like to use LiDAR scans to reconstruction thin wires but use photogrammetry for the other parts of the model (lower half).

Some advice would be much appreciated, thank you!
