Another couple of very brief points:
1. The word wisdom is of the feminine grammatical gender in most ancient, and many modern, languages. English is one of the few languages which does not have this property. It is a fallacy to conflate grammatical gender and "actual" gender/sex, much less comstruct entire theologies around it. What would those who wish to proclaim the "feminine" God make of Logos or Word, which is, in most languages, either grammatically masculine or neuter?
2. The Protection of the Mother of God is not a mere "concept"; the feast commemorates a miraculous event, witnessed by many people.
3. There is no Orthodox feast dedicated to the Wisdom of God. There are no feasts (unlike in the RCC) of the Orthodox Church which commemorate ideas or concepts, such as "the holy name", or similar. Liturgical commemoration is the verbal counterpart to iconography: both deal with the revelation of God, through His incarnation, or through His Mother and His saints, not with the personification of attributes of God.
