I would say no. Grant proposals are a precious commodity, especially in this day and age of reduced funding and evaporating money. However, in a recent Nature correspondence, Dr. Noam Harel describes his vision for a centralized grant repository, ideally open to the public, where researchers could place their best ideas, allowing various funding agencies to discover the plans most-suited to their respective agendas. Dr. Harel likens this potential web manifestation to something like eBay, Facebook or Google, but for scientists and funding agencies. A more apt analogy might be Monster.com, with both sides searching for their ideal match, and a long-term relationship (perhaps I am now making it sound more like eHarmony.com…).
