I can do the simulations as below :-
1) Remove an ACE from double deck, shuffle those remaining 103 cards.
2) Insert randomly that ACE between 1st and 6th card.
3) Play head up with dealer using basic strategy and record the win/loss
4) Shuffle after each round.
5) Repeat above for million rounds to calculate the EV
Is that what you want ? Please note that I did the similar sim for my own game.
