I'd think something like
this would be alright.
if you switched weapon mastery and imp intercept, DW and SS on the talent tree. you could probably swap a point out from d/w spec to put into imp execute, if you where so inclined.
I did think switching to a slow offhand would be useful for "warrior stormstrike". Since your dealing only 50-62.5% offhand damage anyhow... switching from a 100 dps OH at 1.5 speed (150 average) to a 100 dps OH at 2.5 speed (250 average)... ok, lemme do this right;
Examples;
With 2800 AP (200 DPS), For OH.
100 DPS 1.5 Speed vs 100 DPS 2.5 Speed. Example with d/w spec 5/5.
The 1.5 speed equates to 187.5 DPS or an average of 281.25 damage.
The 2.5 speed equates to 187.5 DPS or an average of 468.75 damage.
A difference of 187.5 damage per hit.
This is the same argument related to Devastate; Fast or Slow. But this time, it's your offhand.
This means also your OH will not be consuming your flurry charges as often as well, if you switch to a slow OH.
Yes, spikier rage generation. Yes less time between Flurry procs from white damage (which is not a big deal really, skills like WW and BT will have higher related intervals to flurry consumption).
::EDIT::
realized you meant to max out imp ww. I don't recommend that. As pointed by Rrzip earlier, it makes you trip over your cooldown with BT at max 2/2. 1/2 means you should feasibly never trip over each other cooldown... or much less often.
