Sacrilege
Aha. Well for parnassah we can also live on a bare minimum. We can wear second hand clothing..but nobody wants that!!
Judaism isn’t about doing the bare minimum. A single girl should not be cutting corners. A married woman who has kids and is busy taking care of them has all the Halachic excuses. You have none except your contrived ones of course.
Most Halachic authorities hold like the Ramban that a woman must daven shacharis and mincha. The minimum is 2 shemonah esreis a day. I know you are a lawyer but there aren’t real loopholes for a single girl.
