Definitely won't be added as a setting, since that's quite outside the scope of the mod.
As a standalone mod... what you're asking for is just the ability for a chemical plant to directly freeze the fluid form into the solid variant introduced by this mod? (and likely the inverse process as well, when not playing with Reverse Factory).
Hmm, technically speaking, that should be possible; I should just be able to extract the fluid making part of the code from this mod, then duplicate and invert part of it to make the freezing side of each recipe. Then probably add a setting to hide the barreled form, since you wouldn't need/want both processes.
An interesting concept; I'll look into it when I can (likely won't be able to start it until Sunday). And as for the compatibility with that BigBags mod, I'm not sure what part of it would conflict with either Reverse Factory or the suggested standalone mod? If all it does is increase inventory size? And I guess stack size?
