With a rod it may be hard to pull off casting the spells and send the two-handed blade on it's way.
Once you can afford it (i guess it could take a while), combine it with a nice "Glove of Casting" (MIC, 20k), so you don't have to actually hold the rod to use it.
EDIT: personally, i'm planning on putting the spell in an Eternal Wand (since it's not in the Duskblade's spell list), and in a wand chamber. I think there's a feat or item out there that allows me to use metamagic with wands, but i'm kind of feat starved too...
