1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.c3 dxc3 5.Bc4 Nf6!? 6.Nxc3 Bb4 7.e5 d5!, ..... I think Black is not worse and may have a slight edge in the arising endgame.
I disagree. 8.exf6 dxc4 9.Qxd8+ and the only question is if White's initiative provides more than just sufficient compensation. White can always use his/her initiative to simplify to a dead drawn endgame, because of the Bishops of opposite colours. After Nxd8 10.fxg7 Rg8 11.Bh6 Bxc3+ 12.bxc3 Ne6 White's results always have been excellent.
I understand your desire to cut some theory here, but I think with this line you pay too heavy a price. An option that might take White out of his/her comfort zone is the blockading strategy from Nyholm-Alekhine, Copenhagen 1912: 4...d5 5.exd5 Qxd5 6.cxd4 Nf6 7.Nc3 Bb4 8.Be2 Ne4 (though you might prefer to play Bf5 before castling, like Alekhine did). From a positional point of view this looks far more attractive for Black than that Queenless middlegame line.
I analysed this line many years ago and concluded that Black is OK after 1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.c3 dxc3 5.Bc4 Nf6 6.Nxc3 Bb4 7.e5 d5 8.exf6 dxc4 9.Qxd8+Nxd8 10.fxg7 Rg8 11.Bh6 Ne6 12.0-0-0 Bxc3 13. bxc3 and now 13...f6 14. Rhe1 Kf7 and it's a game.
Then if 15.Nh4 Nc5 aiming for counterplay seems the best way to handle it, rather than rushing to capture the g7-pawn. White's best try might be 15. Re4, answering Black's most ambitious response 15...b5 with 16. Rd5!?.
The chances seem about equal, but it's tricky and my old analysis was not not engine-checked, so "caveat emptor" and all that.
Black definitely needs to know what he is doing, so I'm not really disagreeing very strongly with MNb, whose judgement, especially of open games, has proved time and time again on this forum to be pretty reliable and certainly always worth our attention.
