Respectfully, I think you miss the point of the paintings of Jesus on the cross. For Christians, they are representations of what really happened and not some abstract symbolism. The point for Christians is to look at such paintings and reflect on Christ's sacrifice.

Similarly, paintings of Jesus as a baby are representations of what really happened and are invitations to reflect on how God came to earth.

A mishmash like this is meaningless and unrepresentative of the reality Christians reflect on daily because of the simple fact that it didn't happen and no one claims it did.
