I love this idea, but why not add a propane grill as well? Every non-restaurant grill I've seen has been propane. This poses a glaring flaw, however: how do I get propane? Well, irl, it is a byproduct of refining crude oil into gasoline. Maybe if BC is installed, use its oil, bit if it's not, gen your own oil. Then you could add a multiblock refinery to separate propane from gasoline. This has the bonus(?) of giving you gasoline to use how you see fit.
