Upgrading a 2011 2.5i Limited with newer features?

[OutbackBee]

Hi, I just bought a 2011 2.5i Limited in Red that I am absolutely in love with. Besides the normal upgrades (new bluetooth receiver, Viper system, replace oxidized headlight, etc), I wanted to know if I could upgrade some of the older features to newer ones. For example, would I be able to replace my heated mirrors with the new auto dimming mirrors with the approach light? I think my rearview already has the auto dimming feature, but I'd replace that too if I had to. Also, could I replace my current headlights with the new steering adaptive headlights? I plan on driving this car until it dies (lol) so I don't mind it it costs a a little more, but nothing too ridiculous. Thanks in advance!
