To 1 and 2: These versions are nearly similar but: The version 1 makes
black still stronger than white. The version 2 is clearly weaker than
version 1 in the case the Goldrider is no defensive piece. If white plays
well he will get behind the Goldrider and then it is much easier to win
for white.
To 3: This variant looks much better for me but there are still issues in
the case if black pawns can be promoted to Viceace or not. If they can
then it would get very easy for black to win. If they can not then black
have lesser useage of the pawn promotions and this counts for promotions
into king too.
To 4: This sounds the best way. Add knight move to the king and make both
retain and be promotable from pawns.
