That is just utterly bizarre fantasizing. You don't drop the core of the party platform, discard your voters, and seek their replacements from the party that you just copied.
All you are doing is calling for the end of the GOP, and the end of a party for conservatives, and an end to resistance to abortion and the left, on social issues.
What is your game?
In what way is it "dropping the core of the party platform"?
Here is the entire platform from 2012:
"All you are doing is calling for the end of the GOP, and the end of a party for conservatives, and an end to resistance to abortion and the left, on social issues."
Those who feel strongly about such issues can promote them. I think it will be most effective at the state and local level. Despite the 2012 platform above, the perception of the Republican party as the party of intolerance and religious extremism was enough to sink it. It also didn't help that we fielded a subpar candidate, of course.
"What is your game?"
Keeping the Dems from running the country into the ground for four more years (at least). Looking into the future, and the likelihood of amnesty for the illegal aliens who are very likely to be Dem voters, we need to increase our appeal outside the party. It's that simple.
