You can’t do this for the same reason you can’t use the verb to be in the Perfect-Progressive aspect:
Past – Perfect-Progressive
He had been being happy. [Active]
To be is a stative verb, meaning it is expressing a state of being, and these words cannot be used in the Progressive or the Perfect-Progressive aspect. For example, know is a stative verb:
Present – Simple
He knows the answer. [Active] ✔
Present – Perfect
He has known the answer. [Active] ✔
Present – Progressive
He is knowing the answer. [Active] ✖
Present – Perfect-Progressive
He has been knowing the answer. [Active] ✖
However, to be is confusing because it can sometimes be used in the Progressive aspect. Normally to be refers to something existing, like:
I am alive.
You are a student.
He is from Cambodia.
But the phrase is/was being can refer to how someone is behaving. Because of this, it can sometimes be used in the Progressive aspect. For example:
Past – Progressive
He was being very rude yesterday. [Active] ✔
Present – Progressive
He is being very rude today. [Active] ✔
This is okay, because it is talking about how someone is behaving. It is the same thing as saying:
Past – Progressive
He was acting very rudely yesterday. [Active] ✔
He was behaving very rudely yesterday. [Active] ✔
Present – Progressive
He is acting very rudely today. [Active] ✔
He is behaving very rudely today. [Active] ✔
But when to be is talking about existence, it can’t be used in the progressive aspect. For example:
Present – Progressive
I am being alive. [Active] ✖
You are being a student. [Active] ✖
He is being from Cambodia. [Active] ✖
To be can never be used in the Progressive aspect with any additional auxiliary verbs.
This means:
1) That To be can never be used in the Perfect-Progressive aspect because the that aspect adds the auxiliary verb to have to the Progressive aspect.
Present – Perfect-Progressive
He has been being very rude today. [Active] ✖
2) That to be can never be used in the future tense of the progressive aspect, because it adds the modal verb will:
Future – Progressive
He will be being very rude tomorrow. [Active] ✖
3) That to be can never be used in the progressive aspect with any modal verbs:
Past – Progressive
He could have been being very rude yesterday. [Active] ✖
He may have been being very rude yesterday. [Active] ✖
He should have been being very rude yesterday. [Active] ✖
Present – Progressive
He could be being very rude today. [Active] ✖
He may be being very rude today. [Active] ✖
He should be being very rude today. [Active] ✖
