I'd imagine Cecil would work but it might be overkill - you could just use .NET
reflection:
try:
raise Exception()
except:
import sys
tb = sys.exc_info()[2]
tbtype = type(tb)
import clr
import System
clr.GetClrType(tbtype).GetField('_next',
System.Reflection.BindingFlags.NonPublic|System.Reflection.BindingFlags.Instance).SetValue(tb,
None)
Just replace None w/ the value you want to set it to. For 1.x change '_next'
to 'next'.

Could you use something like Cecil for this?
