I think IW/Silver is the right call here. The important card is the Wharf, and you will likely get it in shuffle 2 with this opening. Of course it's a bit more likely to miss, but it's not that high.
And as you want this villages, it's basically a nonterminal Gold with +buy when you gain Villages, with some other options (Copper that gains you a Silver).
It's not that important to get the IW early on this board than on other Village/wharf boards, because there are 2 real Villages and Shanty and Nobles, so you can't get locked out of the Villages, but you also can't get locked out of the draw because of CR and Nobles.
I don't believe in Tactician here, the money comes from the Treasure, other things are too complicated (Village/NC, Oasis) considering that Wharf also gives you large starting hands without forced discards.
Village vs. WV. Only 3piling, but that not really an issue at T4.
