It might work. But like I said, I'd use the KAC buffer or at heaviest a BCM H. KAC knows how to build a good rifle. If it needed a super heavy buffer it would come with one.

Yeah, but they didn't build that buffer setup for the 11.5'' with .071'' gas port + Noveske SB.
What do they run on the 11.5'' SR-16 CQB?
Also:
I have purchased three Sprinco blue springs, and 3 BCM H3 buffers.
I'll post how it runs after 1K rounds.
Thought I'd post these threads/pages for relevance as they contain useful information, and helped me out.

The Big M4 Myth: “Fouling caused by the direct impingement gas system makes the M4/M4A1 Carbine unreliable.” by Mike Pannone

.071" is what Noveske and LMT use on 10.5" barrels. On 11.5" barrels it should be even more reliable due to the longer time the bullet is in the barrel. Both companies recommend H buffers. A Noveske switchblock doesn't magically add more gas on the normal open setting. It only restricts some gas on the suppressed setting. I'd still recommend nothing heavier than a H buffer with a normal rate chrome silicon buffer spring.
You can over buffer a gun just as you can have an overgassed gun.
On my 10.5" SBR I'm using a Colt M4 SOCOM barrel cut to 10.5" gas port left at .062" along with a standard BCM bolt, LMT enhanced carrier and a BCM H buffer. It shoots soft suppressed and unsuppressed REALLY soft and still locks back on an empty mag. Even softer using a H3 but won't lock back on an empty mag when unsupressed with a H3.
What spring are you running?
Is .071'' a better port diameter than .063'' or is .063'' for dedicated suppressed rifles?
I'll dig up my KAC buffer, and play with standard H buffer and see what happens.
