Lexington dreadnoughts in the Dominion War

What if Starfleet replaced its entire capital-ship fleet with Terran Lexington dreadnought cruisers during the Dominion War?

Their extra phasers, torpedoes, lance and weapons pod are expected to give Starfleet an overwhelming firepower advantage.

The proposed Lexington ships carry more weapons than the Odyssey comparison used here. Phasers, torpedoes, a spinal phaser lance and a weapons pod are the reasons given for a strong advantage. Replacing Starfleet's entire capital-ship fleet with them is expected to overwhelm Dominion opponents. That prediction concerns tactical firepower within an in-universe counterfactual, without a separate assessment of production or logistics.
