I feel like the better option would have been to have the G.I.R.L lab established, then shortly afterwards introduce a problem (villain or otherwise) that requires them to all come together and collaborate on a science-based solution. Having the series' ticking clock be an actual threat - as opposed to just a science fair - probably would have helped maintain intrigue, as well as make it seem like the girls were more directly involved in something important.
