Bought a new (for me) 2018 Yaros hatchback, I miss my 2013 Yaris SE

[Brunno One]

This is my 5th car with the 1NZ-FE engine.
Yesterday July, 6 2020 I bought a new to me 2018 TOYOTA Yaris hatchback. Being owner of many of them I know that the 1NZ-FE 1.5L engine is reliable. My previous car was a TOYOTA YARIS SE or simply "S" that had many features my new 2018 Yaris doesn't.
I don't have power-mirrors on my 2018 Yaris
I don't have the RPM Tach on my 2018 Yaris
I don't have the nice side skirts or flares on my 2018 Yaris.

Can I buy the side skirts / flares for a 2013 Yaris S / SE hatchback and put them in my 2018 Yaris?

Can I put power-mirrors in my 2018 Yaris?

Does the 2018 Yaris came with an RPM tachometer in the top models? (S / SE) Can I modify my instrument cluster to the one that has the RPM tachometer?

Also...
Where can I find or buy that nice set of tail lights?
