If you're unhappy about 'er indoors fanging around in it and kerbing the alloys etc then just leave it as is, keep the battery connected but put 45+psi in the tyres to avoid flat spots. Also fill it with fuel to avoid condensdation in the fuel tank.
I leave all my cars like this every winter and 9 times out of ten they just start straight back up again. The worst scenario is that you have to recharge the battery, no downsides, no problems, no big deal.
