The standard drawkiller opening setup is virtually lost for black. I have tested this position many times and in almost every game black is losing. The problem lies in the weak pawn on c7. If the King stand on b8 instead, that pawn can be defended and a vital tempo is not needed to used on that.
Black is severly underdog with the King in the corner. Pawn on c7 is the new f2/f7 achilles heel essentially.
1. e3 d6 2. Nh3 Nc6 3. Bd3 Be6 4. O-O Qd7 5. Kh1 O-O-O 6. Re1 Kb8 7. Bf1 Ka8 8. Ng1 Qe8 9. Nf3 Bc8 10. Ng1 Nb8

These are the two move-sequences, which create the „SALC“-like king- and rook-positions on the chessboard:
1. e3 d6 2. Nh3 Nc6 3. Bd3 Be6 4. O-O Qd7 5. Kh1 O-O-O 6. Re1 Kb8 7. Bf1 Ka8 8. Ng1 Qe8 9. Nf3 Bc8 10. Ng1 Nb8
1. d3 e6 2. Be3 Bd6 3. Nc3 Nh6 4. Qd2 O-O 5. O-O-O Kh8 6. Kb1 Re8 7. Ka1 Bf8 8. Qe1 Ng8 9. Bc1 Nf6 10. Nb1 Ng8
My point is that this position is more balanced.

Alternatively perhaps this modification can be done.
White can castle queenside, black kingside. 0-0-0 vs 0-0 counterbalance each other as white starts.

So what?!
First of all: I never said, that it could make any sense, to play games from the Drawkiller starting position. All my Drawkiller openinglines add several pawn moves to this starting position and all endpositions of these openinglines were checked by Komodo.
Second: The Drawkiller Elo-Zoom openings base on a different starting position, with rooks on a/h and Kings on b/g. But the same here: It is a stupid idea, to use the Drawkiller Elo-Zoom starting position for playing. All Drawkiller Elo-Zoom openinglines add several pawn moves to this starting position and all endpositions of these openinglines were checked by Komodo, too.

From there (always a good idea, to read, before writing...)
The Drawkiller EloZoom lines look different and lead to different non-pawn piece-patterns on the board:
1. e3 d6 2. Bd3 Be6 3. Nf3 Nc6 4. Kf1 Kd7 5. Kg1 Kc8 6. Qe1 Kb8 7. Qd1 Qe8 8. Bf1 Bc8 9. Ne1 Nd8
1. d3 e6 2. Be3 Bd6 3. Nc3 Nf6 4. Kd2 Kf8 5. Kc1 Kg8 6. Kb1 Bf8 7. Qe1 Qe8 8. Bc1 Qd8 9. Nd1 Ne8
(The kings are on b and g, the rooks stay on a and h and the knight, which was on the field, the king is now, is on d or e) - the main ideas of Drawkiller stay the same here: Kings on different sides of the board, queens not on the same row, all non-pawn pieces on the 1st and 8th rank...
The Drawkiller openings were filtered out of this raw-data with Komodo 11.2.2. Komodo checked all endpositions (using pgnscanner-tool), running on a i7-6700HQ 2.6GHz Notebook (Skylake CPU) with all 4 cores and 2048 Hash, Contempt=0.
.... No endposition of any Drawkiller opening gives a huge advantage to white or black! Especially the Balanced and EloZoom files have very small eval-intervals. I believe no other opening set has such balanced endpositions...
