Middle name?

I love the name Saoirse (pronounced SEER-sha) as a middle name - it’s Irish Gaelic for freedom. I also loved the named Sorcha (meaning light) until I learned that it’s supposed to be pronounced SUR-ka and not SOR-sha. I’m mindful that it’s hard to pronounce and written in Gaelic and not English, but also that middle names are often really more for parents since kids don’t have to write them out that often. One option I considered is just spelling it like Sorsha (like the character in the movie Willow), but also realizing that it strips the name of the beautiful meaning. Any thoughts?
