Nah. Put up the tent and put the shed in the tent. Keep the tent bag in the shed.
The benefits of being able to check the tent for leaks any time before departure are pretty obvious.
I'm surprised that you didn't suggest it. @

Oh, and as a bonus, if there's a deluge the day you need to strip the tent to pack it for your holidays, the tent bag will be dry and will stop the boot of the car from getting wet.
