Shooty Orks?

Well the Necron codex is out and at this point I'm feeling Close Combat is definitely not worth it any more. My games with my Orks have all recently boiled down to: race forward, jump out of Battlewagon, Assault Rhino/Chimera. Kill aforementioned Chimera/Rhino. The Ork Squad of 20 disappears to swath of Heavy Flamers, Multilasers, Psycannons, Missile Launchers. If any Orks Survive they normally get to assault and wipe out either the squad from the Chimera/Rhino they destroyed on the previous turn or attack another one.

My local meta has just devolved into troops in mobile bunkers, and Close Combat is just not cutting it.

So here's an idea, probably half baked and will never work, but I give you shooty MSU Orks:

HQ
110 -Big Mek - Kustom Forcefield & Burna - Will be in one of the Trukks

110 - Big Mek - Kustom Forcefield & Burna - Will be in one of the Battle Wagons

Elites

150 - 10 Lootas
150 - 10 Lootas
150 - 10 Lootas

Troops

110 - 10 Orks with Shootas, 1 Rokit Launcher, Mounted in Trukk with Rokit Launcher
110 - 10 Orks with Shootas, 1 Rokit Launcher, Mounted in Trukk with Rokit Launcher
110 - 10 Orks with Shootas, 1 Rokit Launcher, Mounted in Trukk with Rokit Launcher
110 - 10 Orks with Shootas, 1 Rokit Launcher, Mounted in Trukk with Rokit Launcher
110 - 10 Orks with Shootas, 1 Rokit Launcher, Mounted in Trukk with Rokit Launcher
110 - 10 Orks with Shootas, 1 Rokit Launcher, Mounted in Trukk with Rokit Launcher

Fast Attack

70 - 2 Warbuggies with TL Rokits
70 - 2 Warbuggies with TL Rokits
35 - 1 Warbuggy with TL Rokits

Heavy Support

150 - Battlewagon - Killcannon & 'Ard case
150 - Battlewagon - Killcannon & 'Ard case
150 - Battlewagon - Killcannon & 'Ard case

Overall shots In perfect world

10-30 Str 7 shots Deffguns
12 Rokit Str 8
5 TL Rokit Str 8
3 Str 7 Ordanance shots
108 Str 4 Shoota shots
2 Burna Templates/Power weapon hits

Deployment would most likely be either Hammer and Anvil - Hammer being all the Buggie and Trukks on one side and the 3 BW and 3 lootas being the anvil. With 2 Meks centrally located to spread the Kustom Forcefield as much as possible.

OR

2 Prong - Split up the force evenly as possible,
Force 1 -Mek, 3 trukks, 3 buggies, 1 BW
Force 2 - Mek - 3 trukks, 2 buggies, 2 BW

With the Lootas providing covering fire.

Opinions?
