internship and study abroad right before application submission

hey y’all! i’m planning to do a semester long internship in washington dc the spring semester right before apps are due and then go on a study abroad that june or july. i plan to ask for letters of rec by the december before, pre write my primary early early so i can revise while i’m in dc, and write secondaries while interning. i’m taking the mcat this august and plan to take it in january if a second attempt is needed. what do y’all think? too ambitious? these are such awesome opportunities so i would be really sad if i had to give them up but i don’t wanna sacrifice app cycle bc to me that takes priority. i think i can balance but wondering if anyone’s had a similar experience/success?
