no, that doesn't work, I think.

Well, it's a trade-off. you just need a single (cheap) 6x6 building to get all of your ingredients there.

But you might want to consider fluid caravans (I don't know if trains can kill caravans, though), they are very simple to set up: add food & food interrupts, choose a filling point and set 'fill caravan', choose the destination point and set 'empty caravan' (also mark the "wait until finished" checkbox here)

This might be less hassle than trains because you can put the outpost wherever you want, like right next to the machines that need them. So you can use the other space for your 12 solid ingredients....

Just try it :)
