I'd guess that you'll want to hit at least around 40 IBU.
This beer is wide open to interpretation though, so go with whatever you think will work for you. The only help I found in the BJCP guidelines were that this beer is supposed to be much more complex than a Düsseldorf Alt, so I tried to make it much more complex.
IMO, a Pils base for this beer along with some Munich and/or Vienna really makes it.
