Well, the combined fleet of the 3067 Inner Sphere Clans (Jade Falcons, Wolf, Ghost Bears, and the one lone Shark vessel) if all the warships were in the Inner Sphere at the time was 40 warships (that's counting even the two ships that were being repaired by the Ghost Bears and the ship that the Jade Falcons lost to Wolves in Exile). Now realistically, it's probably be more around 14 warships since the Wolves and Falcons probably had most of their fleets traveling the Exodus Road, in the Homeworlds dealing with other Clan fleets, or in the Ghost Bear case just getting repaired. (The real problem is that we don't exactly have pinpoints where each vessel is in canon for the time. Also, I'd figure the Word of Blake wouldn't pick a fight with the Nova Cats or Wolves-in-Exile. Also, I'm going to figure that except for the Ghost Bears that the fleets are in thirds between the Occupation Zone, Exodus Road, and Homeworlds.)
The Word of Blake on the other hand had 35 warships going by strictly the original ships of the fleet on page 128 of Final Reckoning. Now realistically, I'm going to cut off forty percent for being built or refurbished at the time. (Honestly, the Word of Blake built some Dantes at some point which weren't captured, and somehow I doubt that they had them ready in 3067 with everything else that was being refurbished at the time between Titan and Gabriel.) That means that the Word of Blake fleet would be about 21 ships in 3067 under my estimates.
If the Word had all their ships on the boarder at the time of 3067, they would have probably smote the Clan fleet not accounting for ship type, experience, tricks i.e. alamos, or even logistical questions. The big problem here for the Word is that they have reserves probably, but the Clans would have more if all the Clans in the Homeworlds immediately go crazy to avenge the Inner Sphere losses which gives maybe four months to a year to rebuild. The possibility exists that Khan Brett Andrews could cause the Wars of Reavings early by using the losses by the Inner Sphere Clans to justify trials of annihilation which would give the Word more breathing room as the Clans whack each other. It's just a question of who could get their reserves there the fastest in the end.
The other issues is ground combat, and that would probably destroy the Word of Blake Militia Divisions if there are not combat multipliers such as NBC weapons involved. The worst area on the ground for the Word would be the Ghost Bear Dominion since it held nearly all of their ground forces.
In the end, it'd be a . . . draw.
