Since He set the ratio at 2/3 will be going to hell on the day of the return it seem like making that ration any smaller is going to be something God isn't going to change no matter what.
thou that didst not bear;
break forth into singing,
and cry aloud,
thou that didst not travail with child:
for more are the children of the desolate than the children of the married wife,
saith the LORD.
God also makes it pretty clear who will be rejected until the Great White Throne event.
I am sought of them that asked not for me;
I am found of them that sought me not:
unto a nation that was not called by my name.
I have spread out my hands all the day unto a rebellious people,
which walketh in a way that was not good, after their own thoughts;
A people that provoketh me to anger continually to my face;
that sacrificeth in gardens,
and burneth incense upon altars of brick;
Which remain among the graves,
and lodge in the monuments,
which eat swine's flesh,
and broth of abominable things is in their vessels;
Stand by thyself,
come not near to me;
for I am holier than thou.
These are a smoke in my nose,
a fire that burneth all the day.
it is written before me:
I will not keep silence,
but will recompense,
even recompense into their bosom,
and the iniquities of your fathers together,
saith the LORD,
which have burned incense upon the mountains,
and blasphemed me upon the hills:
therefore will I measure their former work into their bosom.
Thus saith the LORD,
As the new wine is found in the cluster,
and one saith,
Destroy it not; for a blessing is in it:
so will I do for my servants' sakes,
that I may not destroy them all.
And I will bring forth a seed out of Jacob,
and out of Judah an inheritor of my mountains:
and mine elect shall inherit it,
and my servants shall dwell there.
And Sharon shall be a fold of flocks,
and the valley of Achor a place for the herds to lie down in,
for my people that have sought me.
But ye are they that forsake the LORD,
that forget my holy mountain,
that prepare a table for that troop,
and that furnish the drink offering unto that number.
Therefore will I number you to the sword,
and ye shall all bow down to the slaughter:
because when I called,
ye did not answer;
when I spake,
ye did not hear;
but did evil before mine eyes,
and did choose that wherein I delighted not.
