Are my goals unrealistic?

I’m buying my first PC tonight😁 so gonna lock in this season.

I sweated this game in 2022 and hit GC and have been hovering around C3 for the past couple years, playing here and there.

I recently started playing properly again and alongside being very rusty, I’m also C2 in 2s and D2 in 1s.

I have probably played a collective of 50 1s matches in my whole life and have never gave it any love but this time I want to improve my game sense and similar stuff so I’m gonna be playing a lot of it this season, as well as 2s.

After my upgrade to PC, and the time I can play this game (probably 2 hours a day most days with the exception of a couple days a fortnight I can play for the whole day), I aim to hit GC1 in 2s and C1 in 1s.

Is this unrealistic?
