This would create too high of an SG for a starter. Your yeast will stress trying to ferment all that sugar. 4 oz of DME in 4 cups or approximately 1 liter of water is preferred. That allows the yeast to grow and thicken their cell walls to begin fermenting.
For dregs, I would start with 2 cups of water and 2 oz of DME as a step up starter (you don't really know how old the yeast in your bottles might be). Then cold crash it after 36 hours or so, decant the spent wort and add the slurry to a new 1 liter starter (you can pitch the second set of dregs in with the slurry to this starter) and let it go another 36 hours before cold crashing. On brew day decant the spent wort and allow the slurry to warm up to pitching temperature and you should be good to go!
This is on the presumption that you are not using a stir plate. If you are using a stir plate, then the amount of time would be approximately half. (I only run my starters for about 18 hours, even for a 2 liter starter)
