off the top of my head LBs shoot normaly at a speed of 2 seconds, with CL having a CD of 6 seconds that makes 3/1 ratio, to fit 4 lbs into a 6 seconds you need LBs shooting at a speed of 1.5, aka 25%.
so the way haste works it is a little bit less then 16 haste for 1%, meaning 160 haste makes about 10%, 320 haste is 20%, and 400 haste is 25%. this is a very hard number to reach.
Is this impossible... i want to say no, but the amount of crit you would lose is quite a bit since you would have to sacrafice any yellow sockets for haste, and the amount of time effort and gold you will spend i am sure will be a great amount.
Lets look at what gear easiest to get is out there to use as stepping stones for this goal...
http://www.wowhead.com/?item=34935 34 haste 1 yellow socket
http://www.wowhead.com/?item=34933 51 haste 1 yellow socket
http://www.wowhead.com/?item=34934 38 haste 1 yellow and blue socket
http://www.wowhead.com/?item=34604 18 haste
http://www.wowhead.com/?item=33970 33 haste
http://www.wowhead.com/?item=35319 21 haste 1 yellow socket
http://www.wowhead.com/?item=35320 30 haste
http://www.wowhead.com/?item=35326 40 haste
http://www.wowhead.com/?item=35321 16 haste
http://www.wowhead.com/?item=33334 17 haste
http://www.wowhead.com/?item=33588 25 haste
http://www.wowhead.com/?item=33974 25 haste
A total of 348 (52 short from our gestimated number (about 22%)
but wait we have sockets woot...
http://www.wowhead.com/?item=35761#comments 10 spell haste each
we have 5 sockets this brings us too...398
now i know i said about 16 but i round up, this should be enough to get 25% haste but you may need to shave some haste since it is probably slightly over...
this actualy has not covered all your armor i think this leaves you with 1 trinket, 1 ring, helmet, and boots (i may be wrong lol)
at this point you can fill trinket and ring with whatever you prefer (lots of good ones out there to pick, and for helm and boots I suggest these, since your going all out for crit these are easiest to get and can give you back some of your neglected crit and spell dmg:

for helm i suggest this socket
http://www.wowhead.com/?item=34220
this means fit in 2 blue gems, one on your helm on on your boots i would suggest these:

fun times gonna figure out the bonus spell dmg from all this now...
