If there isn't some coding/performance problem with it I don't see why not - currently you can only manage as many slots as your toolbelt has, and requesting multiple stored items for e.g. expanding your factory makes re-setting your resource/belts&pipes/whatever basic settings tedious. You can just craft items in hand, which takes time, sometimes too much (modules, laser turrets, loads of belts, ...).
It sure seems in the spirit of the game - automated mining/crafting a lot of stuff just to pay for more automation

Btw first post, so: Hi, factorio is awesome, thanks for making it, I have to go play it some more, bye
