I thought that initially, but really, why?
EB adds points to life (yours) on a one for one basis, multiplied by the number of EBs
NF takes away a point of life (your opponent's, via damage) on a one for one bases, regardless of the number of NFs
Differences: with EB there is a good chance that while your life goes up, your opponents goes down, as you only gain EB from creatures (which usually do damage); with NF there is no guarantee that you gain anything whilst doing your damage, so your opponent way just out damage you.
Not really balanced, unless I am missing something.
Also, if you want to incorporate wither NF or EB, you would logically put multiples in your deck. EBs are more useful if you draw a second or third, in this case, making NF fall behind in another way.
