I've tilled our garden with much higher weeds than you're faced with. Go ahead with the tiller, either 5' or 6', doesn't matter all that much.
What I've done is to till it on the first pass very shallow, maybe 2", just enough to cut the top layer. Then on the cross path go down further if you wish. Just remember, the deeper you go the more rocks and other unwanted objects are going to surface.
Much of the grass will get chopped up although you likely will see some green for a day or two. Not much you can do about that short of using round-up or burning. Not a big deal though since you're seeding right away. Soon it'll all look great.
