As far as the economic situation in Stirland, we need to be 100 percent certain that the EIC is there to bail out Roswita when she starts seeing sense, or Stirland is toast. In that vein, allowing Anton to marry any of Wilhelmina's choices is effectively ceding control of the company to her. Anton will be guided by his wife, who will be guided by Wilhelmina. Marrying him ourselves will guarantee us controlling interest and thus the ability to make sure that Stirland's interests will be at the front when necessary, while still allowing Wilhelmina to work her magic and get her cut.
