Daemon Hornblower vs Pink Horror Icon Bearer + Destiny Dice

[Malfean]

How does this particular interaction work? I've been getting mixed feedback on it. Some say the (daemon) Hornblower rule supersedes and forces the Tzeentch player to re-roll their Icon Bearer result even when using Destiny Dice to make it a 1. Others have told me that Destiny Dice supersedes the Hornblower rule most daemon units have. I have put the relevant FAQ and rules below.

Also for the record, the Hornblower rule seems consistent across most daemon infantry and cavalry units.

Page 69 – Battle Traits, Masters of Destiny
Change the final paragraph to:
‘Each Destiny Dice spent only allows you to replace
a single dice roll. If you want to replace a 2D6 roll
(such as a casting roll or charge roll), you must spend
2 Destiny Dice. In addition, any rolls that have been
replaced count as unmodified rolls and cannot be rerolled. They also cannot be modified, with the following
two exceptions:
- If you spend a Destiny Dice to replace a save roll, the
result of that Destiny Dice is modified by the Rend
characteristic of the attack as normal.
- If you spend a Destiny Dice to replace a battleshock
test, the result of that Destiny Dice is modified by the
number of models slain from that unit as normal.’
Designer’s Note: This means that for the purposes of Pink
Horror Icon Bearers, a Destiny Dice of 1 used to replace a
battleshock roll counts as an unmodified roll of 1.’

HORNBLOWER: 1 in every 3 models in this
unit can be a Hornblower. While this unit
includes any Hornblowers, if the unmodified
roll for a battleshock test for an enemy unit that
is within 8" of this unit is 1, that battleshock test
must be re-rolled.

The above is taken from the Bloodcrusher's entry, though most daemon units have some variation of the wording that goes '1 in every X models in this unit can be a Hornblower. etc etc etc'

Per the FAQ, Destiny dice can’t be rerolled. 
so if you use a dd of 1 on the banner it won’t be rerolled by the horn.
