the alien gambit is dubious
What do you want man? First you complain about getting slow positions that end deep into the end game, now you are complaining about positions which are confrontational, risky and sharp. At this point you are complaining to complain.
3.Nc3 dxe4 4.Nxe4 Nf6
If you don't want to play the Tartakower play the alien gambit, I said this in my original post. In order to play the panov per your move order you have to play 3. exd5, which is an exchange of center pawns, so I don't know why you are mentioning other Panov lines. The exchange of the center pawns is more passive then advancing which is the more confrontational line. That is what I am trying to say, I don't know what else to tell you. If you don't want to play passive don't exchange the center pawns.

and in order to play the panov as soon as possible you play exd5 and c4, which pressures the center and gives white Nf3 and Qb3. you can be in the panov as early as move 4, or as late as move 12
