Anyone do compassionate transfer of leftover embryos?

My husband and I received a much bigger bill this year for our frozen embryos. Our clinic increased the bill almost 50%. We have completed our family, and I am struggling with the decisions we have to make about the remaining 4 embryos. Compassionate transfer is still expansive but seems to be one option that I feel I could wrap my head around. Anyone move forward with this? Any advice would be appreciated.
