Every time you clip a gcd in an actual fight you are lowering the usefulness of all that extra skillspeed so its a gamble and may even depend on your connection/ping. More than likely plunge during bloodweapon would be a clip every time at a certain amount of skillspeed but unsure how high it would need to be and may as well forget doubleweaving carve and spit and utilize hardslash for single weave. Theoretically you also lower the usefulness from bloodweapons -recast the higher your skillspeed is.

I've thought about trying this a few times but I clip gcds irregularly with the little skill speed I do have so it probably wouldn't work for me.
