A pronoun proposal

I am tired of seeing they, them, themself, their, and theirs used as singular pronouns. But if we drop the "th" in favor of an "n" then we get some nice sounding words that are immediately understandable to the ear and that do not already mean something else. Thus, I propose the following:

1st person singular	2nd person singular	3rd person singular, male	3rd person singular, female	3rd person singular, no gender	3rd person singular, unknown gender	1st person plural	2nd person plural	3rd person plural
I	you (thou)	he	she	it	ney	we	you	they
me	you (thee)	him	her	it	nem	us	you	them
myself	yourself (thyself)	himself	herself	itself	nemself	ourselves	yourselves	themselves
my	your (thy)	his	her	its	neir	our	your	their
mine	yours (thine)	his	hers	its	neirs	ours	yours	theirs

Examples

If someone says it is neirs, give it to nem.

Each employee should wash neir hands before returning to work.

A person who comes here must behave nemself.

I greet each guest as ney enters the room.
