Halo 5 Forge Map Idea

Hello everyone and thank you for taking your time to read to me

as the title says, I have an idea for a map and a game mode, the map could be on the streets of new mombasa but it would have to be little straight-line map but with several paths to reach the strongholds and capture them(something like Battlefield’s Grind mode where it was a straight-line map and you had to capture and keep flags as objectives)
In each objective would be a Special weapon (Rocketlauncher, Shotgun, etc.)

I’d do it myself, but I really suck at Forge
So thank you and I’ll be reading your comments
