And how exactly will they create 1 million female space marines? And why would they use female for that? The Adeptus Mechanicus doesn't know how to create gene-seed, they can only use those gene-seed that they already have  (I do not believe that the Adeptus Mechanicus has enough gene-seed to create 1 million female space marine).

If the Imperium can take on that number, then it is to use them to create another 1 million space marines.
