The problem is I should "copy" the mod (the original creator should not be happy of this in a first time) and modifity his entire tech tree, and this, each time he would update his mod... And this in 2 versions (Respect Einstein / F*ck Einstein).

I couldnt do this, there are too many problem for doing this.

If someone could do this, it's the original creator of the mod (I can explain to him if he want, but I will not "steal"/"work on" his mod like that).

The No Time Penalty On Research 2 is what you are looking for :
