When Madman is the only way to play multiple Goons, Hermit/Goons will dominate, but here there are other ways (Shanty Town, Embassy), so you won't be working towards one mega turn with Madmen but several somewhat smaller multi-Goons turns (with Shanty Town and Embassy you should be able to have multiple triple Goons turns), and you can use Madman to get even bigger ones. I'd probably open Moneylender/Hermit, I'd want at least 2-3 Embassies and as many Goons and Shanty Towns as I can get.
Getting FGs with Hermit is good, but I wouldn't want more than 3 of them because Shanty Towns to support multiple Goons are more important.
And definitely stay away from any green cards except maybe on your last turn or when all the Goons and Shanty Towns are already gone. Multiple Goons should give you all the points you'll need, so never buy a Province over a Goons. A good rule of thumb for engine building: Yellow = Green = Purple.
