We have the same car! 1st one I've seen that's got all the same stuff.
Anyway, pulling the Brembos and installing your 20's is a pretty easy task then you can decide if you like them or not, and if they will fit. Bit suprised the bolt pattern is the same! Remember to pull off the little washers the factory uses to hold the rotors in place during assembly as they could cause a vibration.
Nothing wrong with putting the Brembo wheels up for a while...
