Same item level as you have currently, with changes you can get from 1-2 weeks of conq and valor farming assuming you start from 0, plus investing a few k gold and running heroics. 22% crit with both hit and exp capped, that profile should be attainable within a week. Further, there are other upgrades that while still not that hard to get, might require more time or some rng luck: Boots from Stone guard, Cloak from Feng, Chest from Garalon/tier chest, Valor Bracers, Valor Helm, neck from Golden Lotus exalted, conq ring, 5.1 faction etc.
Just for the sake of argument I've included a blues only build with a crit value of well over 20%:

That's pretty much how my char looked the first week of MoP, except I had the Brewfest trinket instead of Carbuncle and the 476 crafted chest/gloves. So yes it is entirely possible to attain decent values of crit even with 463 ilvl, sure you might be giving up higher potential str and overall higher sum of secondary stats, but at least it makes fury playable and enjoyable while you grind for better gear.
