I am attempting to make a name for a character and decided on these 4 kanji. My question is, can this be considered a name in Japanese, if so, how would it be pronounced?
This might be an interesting read for you: https://en.wikipedia.org/wiki/Jinmeiy%C5%8D_kanji (Note that this list is supplementary, but that there are laws regarding what people can and cannot name their children.)
My dictionary lists 来夏 as being a female name with the pronunciations of こなつ, らいか, らいな, and らな. No hits on the first two kanji.
