Ultegra Di2 Upgrade path?

Howdy Folks, long time reader, first time poster.

I’m thinking of upgrading the Ultegra 6800 derailleurs and shifters on a Scott Plasma to Di2. Reason being it would be really nice to be able to shift while not down in aero.

Am I correct in assuming I could replace both derailleurs, both aero bar end shifters, and add a 3rd satellite shifter near the right brake lever to allow for shifting?

Anything I’m missing?

Thanks!

A EW-90 junction, at least 1 JC-41 splitters, and at least 5 cables of varying lengths. Not to mention the battery and the charger

the ultegra level brake lever/shifter is supposed to be coming out soon. so that may be another option to keep in mind. Also don’t forget the internal battery charger
