I wonder what NASA is thinking about this? The NASA Commercial Crew program which helped fund the development of the Dragon was funded for manned flight to the ISS. I'm curious if they see this as part of the project scope?
Read the article: "By also flying privately crewed missions, which NASA has encouraged, long-term costs to the government decline and more flight reliability history is gained, benefiting both government and private missions."
The COTS and Commercial Crew program have specifically been made so that Companies can reuse the hardware for other projects as well. This is the exact thing that NASA has hoped for.
