Obviously, I'm in support of the idea. 
Few things regarding your build:
You need AS to recharge in 3.828s or less for the SB BB QS AS chain to be gapless. Currently, yours recharge in 4.32. This half of a second gap would drop your DPS significantly.
What you can do if you don't want to change your build significantly is to put the Hecatomb proc in SB instead, and run SB BB QS SB AS as your attack chain. With the much greater chance to get an AS crit (almost guaranteed, compared to the mere 75% with SB BB QS AS) the DPS drop shouldn't too significant, about 7 points (going from 247 to 240, without including Musculature or Assault).
Now for misc comments regarding the rest of the build.
I'd throw a Kismet +6tohit in there. Does a lot more for your accuracy than a 4th LoTG set bonus. 
The regen tissue in Physical Perfection could be in Health instead, this way you keep the bonus all the way down while exemplaring.
Slotting on QS, BB and SB could be tweaked slightly to reach better enhancement values and set bonuses while keeping the same amount of procs. I'd suggest 4 Makos + a mix in each power. Specifically:
- in QS, Mako Acc/Dam, Mako Dam/End, Mako Acc/Dam/End/Rech, Mako Proc, Crushing Impact Acc/Dam/End, Explosive Strike Proc (QS can take this knockback set, and the proc has a slightly higher chance of going off than ToD).
- in BB, Mako Acc/Dam, Mako Dam/End, Mako Acc/Dam/End/Rech, Mako Proc, Crushing Impact Acc/Dam/End, Touch of Death proc
- in SB, one Acc/Dam HO, Mako Dam/End, Mako Acc/Dam/End/Rech, Mako Proc, Mako Dam/Rech, Hecatomb Proc
Overall between the damage enhancement % on powers and the set bonuses this should bump your total damage % by about 13 or 14.
There's probably several routes to take with your final picks. If it were me, I would either keep Overload and add Burnout instead of Placate there, so I could have 6 minutes of godmoding before a crash (I'm assuming you can do that based on what I know of either power, i.e. activating the second Overload as the first starts blinking; haven't tried it personally), which could be quite useful for AV soloing purposes - not only for the extra mitigation, but for the extra end recovery which would let you attack more freely; or, second option, seeing as you've already got good defenses all around drop Overload and Placate, grab Tactics for better tohit and confuse/fear protection, swap to Body epic and pick Superior Conditioning on top of Performance Shifter for an extra end proc and slightly better recovery.
Example build to illustrate the above suggestions:

Thanks ever so much for the detailed reply.
Made the change to pick up Burnout and Overload for the "fun factor" that Tactics just doesn't supply The extra slots went into the Panacea proc and a Numina +Heal in health for a bit more regen and recovery.
Also liked the idea of double end bonusses with the Body epic. There are recovery options within the secondary, but they just waste time. Pushed them further up the build (selected at 38 & 41) to take advantage of them as I level.
It was mainly your assessment of the attack power slotting/selection that's really helped. I plugged your build into my attack chain calculator, and was very surprised to see how much of a difference that extra SB made. Not only does it provide a gapless chain, it increases the chance of an AS crit significantly.
The only change I made there was to swap out the HO in SB with a Hetacomb A/D/R (+5'd) for the extra recovery. I think deciding between the two will probably be something I think about when I'm 50.
Thanks again for your help. Much appreciated.

Hi folks.
I loved my KM Stalker and waited with great anticipation for Concentrated Strike at 32.
Wow. That animation sure 'aint my cuppa. And it's not so much the speed of it, more the wavy hands :shudder:
So rather than delete, I thought about building without it. Especially after reading this thread (as well as Gecko's thread on running without CS) although I must confess I didn't get my head around it all.
This is what I came up with:
