measure development – removing items from an item pool due to ceiling effect

During the early stages of scale development, many items within our item pool were found to have a strong ceiling effect with low score variability. In order to attempt create a meaningful measure with useful score variability, the decision was taken to reduce the size of the item pool and only include items with the most central mean scores and the largest standard deviations. Only these items were put forward into subsequent exploratory and confirmatory factor analysis. Two questions. One – does this seem sensible? Two – can you suggest examples from the literature where the same has been done or is recommended? With thanks.
