Is it weird to use 2 middle names? PLEASE read description before voting. Names are in the description.

My daughter is due next month and we've had her first and middle name (Elena and Sage) picked out for most of the pregnancy. Elena is a name that my husband and I just really love and Sage is after my cousin who passed away when I was around 3 months pregnant. She and I were very close, we grew up together and I want to honor her. But then my childhood best friend died last month. I've known her my whole life and she was going to be my daughter's godmother. I loved her like a sister and it just feels right to also include her name, Celeste. That would make her name Elena Sage Celeste. We like it, but quite a few people have told us that it makes her name too long and makes it not flow very well. And I can't just make her name Sage Celeste because it would be too painful to say her name all the time. I'm not sure what to do.

If it IS too weird to have 2 middle names, which name should we use? Elena Sage or Elena Celeste? Or neither?
