It is easy to see, where you are going.
What ever you say, believe or propagate, you will never be able to diminish the physical aspect of Salat and Soum. People have tried before and failed. You are only disrespecting Allah's commands. Fasting is not like a jail for culprits and prayer is an actual physical act at the times given.
I have read Dr. Shabbir and GA Perwaiz, and many more, and not on just pocket note books, enough to know that they never seconded this thought. They never advised that one should forget performing prayers. All they say is that there should be a soul in it and actions of individuals and society should reflect the learning, which at present is not happening well, but doesn't mean it will never happen.
All you are doing is trying to smear the physical duties, ordained on mankind.
Salat is not done while walking or in bed, as you say you do.
Let me know after ten years, how many have quit physical salat and Soum for you, or as per you, including your friends & family. The answer will be zero.
Such Liberalism is a mental disorder. You should return to Balances and moderation.
55:8 So that you, too, never violate balance in your lives.
