Great idea. Won't happen. So, not really such a great idea. Just getting the stuff to where the rocket is will take more than the hour. Then it has to be loaded and secured. Then the rocket has to be fueled, because you can't sit there with uninsulated tanks of liquified gases just waiting in case there is something. A launch tower is a big enough undertaking that you can't afford to squat it, even sitting empty. Best case, you have a fully loaded can sitting dry and out of the way. You roll out a booster, roll out the can, shift the can on top, and fuel them. That's your hour already, at best, assuming a booster is at hand. Maybe you keep a booster idle, too? Where it is supposed to land, where it won't fall over, and where a possible deflagration is OK, is another problem I won't go into. Then, unloading whatever it was. Just getting it to the ground to put on a truck is a big job. You could imagine a 40-ft container stood on end, with hardware surrounding it to snake it out of a hatch and down, with cleverly placed wheels to roll down the can side, and then away to lay it out. Maybe the wheels are road-ready? You can dream. Maybe you could unship the Raptor engines, after, and send them home with their bells cut off. I estimate the scrap value of the rest of the can at maybe $40,000, 60 tops. You are certainly not lofting it ever again. Rolling stuff into a C-17, flying it out, and rolling it off will almost always be faster, and always overwhelmingly cheaper and less likely to explode with >15 ktons of blast energy. It is what they are for, so having them kept ready and fueled up is not a boondoggle.
