Brick Soldiers Arched Entry

I need some help here how to model this soldier brick for a porch entry. The project was designed in 2017 with an another modeling software and used only the 2D representation for soldier course. Now I have transitioned to AC in 2024, I am recreating the old projects in AC. All the bricks are modular 7 5/8 length x 3 5/8 width x 2 1/4 height. Mortar 3/8 thick.

My workflow: Core walls as basic or composite (if either sides with gyp. board), sheathing skin to finish skin as CP Wall w Offset modifiers. This gets easier to offset the sheathing and other skins to mud sill and the bricks' skin to foundation ledge.
