みいか sounds like a Japanese name.
It didn't exist as a Japanese name in the past, but young people tend to give names like this to their daughter these days.
みか and みい are both popular names.
みか is written as 美香, 美佳, 美嘉, 実花, 美華, 未佳 and many more.
It is not impossible to read these as みいか, so this is one option.
Another option is to combine the Kanjis used for みい with a Kanji for か, such as 未依 + 香 and 美唯 + 花.
The last option, which I don't recommend you, is to use 当て字.
当て字 is to use Kanji that doesn't correspond to Kana; this means nobody can read it at first sight.
Reading 神酷似/神似 as みいか is this type of Kanji usage.
Such a strange Kanji combination is what either Japanese learners or stupid parents prefer.
Additionally, 酷 means terrible in Japanese although It seems to mean cool in Chinese.
