As I suspect there won't be any ward data currently in, the idea sounds somewhat appealing, BUT I have not yet seen anywhere where imported boundaries have been done well and have spent many an hour tidying up the results (recently in Haiti and ongoing in GA, USA). Examples include adjacent areas using overlapping ways rather than a single shared way, an admin boundary being imported as a single way which then needs splitting (and any duplicate ways de-duplicating) before a relation can be created, and so on. If such an import were to be done, it should be done well or not at all.
