In terms of raw power, IBG remains unchanged, and thus still inferior to TF. The only meaningful positive changes were the slow radius and the extra CDR:

- the slow radius is mostly irrelevant, since Wither is going to be up basically all the time. If you're getting gangbanged and like the AoE slow, then it's good, but otherwise it's irrelevant;

- IBG got an extra 10% CDR, but so did TF. So the difference in CDR between the two items is still 10%. Nasus's essential items are Frozen Heart, Spirit Visage, and Sheen, and that's 40% CDR already, if your Sheen goes into IBG then it's 10% CDR you're wasting. The other possibility is you're changing FH for IBG, which sacrifices some extra defensive stats for extra damage early on, but ends up leaving you with subpar defense (IBG's defense < FH's) and subpar offense (IBG's offense < TF's);

Moreover, IBG still has some inherent faults compared to TF: AoE damage makes it a bit harder to take turrets without drawing aggro, and it gets harder to stack. You do get better waveclear, though, although E should be handling that pretty well.

TL;DR: is it viable? Definitely. Is it good? Definitely. Is it IDEAL? Probably not, at least not most games. I've been watching and playing some Nasus and FH->TF seems and feels better than sticking IBG somewhere in the build. Although you should try IBG out and see how it plays out for yourself, your opinion might differ from mine.
