I fear if you try to make a full 5 gallon batch that the body will be very light, but its up to your preferences.
That's kinda what I did...
I brewed this beer yesterday and kept sparging after I had collected enough for the first boil.
I did two separate boils ended up with about 5.5 gallons at 1.093 and a solid 3.5-4 gallons at 1.062 (this included about a gallon from the first boil which wouldn't fit in the 6.5ga carboy). I figured the second batch would be a lot weaker, but no... It's noticeably thinner than the first one, but I wouldn't call it thin.
I wasn't really planning on the second batch, so I ended up re-using some of the hops and pitching some dry, champagne yeast. The first batch, which got a proper starter, is bubbling away like mad, but the second is a lot
For the sake of efficiency, this is definitely a good way to brew. You only add a couple of hours to your day and end up with two batches. I think I'm gonna try this with a double IPA and an ordinary bitter sometime in the near future.
