Can my Scorching ray char clear pinnacle bosses?

Hi I absolutely love this skill and the Elementalist version of it with the golems and poured my heart and soul to push it and would love to make it so I eventually am able to clear and beat all the game's content including the pinnacle bosses(at least the non-ubers).

After asking around a bit in the community it became very apparent to me from hearing a lot of doom-saying from others regarding this type of build for endgame content -- I have never gotten to pinnacle bosses before and so I have no clue what is expected from a character in terms of stats to acomplish going through them;

In other words I'm need of an expert opinon from experienced players wether my current build's defenses and DPS are sufficient enough to attempt pinnacle bosses and if not then how far away am I so I can adjust my expectations/goals for this league accordingly

(first time importing a build so sorry if there's something missing, but I did my best to set everything in configuration correctly. after some trouble I managed to also set SR with max stages for the edps)

Appreciate any feedback or help in advance.
