One thing I wondered about, did the WoB do any good works in the Periphery, and if so, what?
Did they send around ships with school materials and tool/die shops, to help upgrade the tech level of the various planets? I.e. if the planet is stuck in 19th century tech base because everything else has been lost, the WoB provides the books and starter tech kits to let them bootstrap? Or if the planet is spending 99% of its industry just on maintaining its current tech base with nothing left over to increase it, the WoB ship can come in and provide the necessary slack so they can catch up. Or a planet has a disease, and WoB provides a dedicated medical ship that can send data back to Terra for aid (with either Black Box or HPG connection).
Or fund mercenaries attacking the Clans, trading 2:1 for any Clan tech they find (i.e. The mercs provide a Clans ERPPC, the WoB trades them 2 Star League ERPPC). Provide missions to go in and grab Clan tech/supplies on planets? Help fund missions to simply drop off aid packages to civilians trapped behind Clan lines, but the packages have convenient phrasing about who provided the supplies, so people thank the WoB instead of one of the Houses. Fund defensive agreements on the remaining Rasalhague worlds, so mercenaries helping out vs the Clans can get more/better contracts.
Maybe provide Mechs to Comstar at-cost, where Comstar pays for the raw materials and no profit for the Mechs being produced (but WoB sets up the toys and advertising campaign, making much more money than the program costs them).
Potentially even providing a ship or ships with supplies to help out with Operation Serpent (and for themselves, they perform
Operation Paperclip on any Clan Scientists/Technicians/equipment/etc). Be fun to have them in a story, where the WoB representative acts as though they are doing something suspicious the entire time, but in reality they aren't. The goal is to get all the suspicion created and resolved before thy get to the Clan worlds, so they can do the suspicious stuff afterwards.
