[3.5] Illumian Factotum

[Kaustic]

In a Gestalt game we are playing, I had the idea pass through my mind of using an Illumian as my base race. From this my Favored Class would be a Factotum. My progression is such: Factotum 20//Wizard3/Master Specialist 3/Geometer 2/Master Specialist 7/Thaumaturgist 5.

Our DM only allows us to Prestige class out of the Secondary Class(in this case the Wizard.)
I am going with a Focused Specialist(Conjuration) with the Immediate Magic ACF as well(10 ft. teleport as an Immediate Action, Int/Day).

The real question I have is about how the Sigils of the Illumian interact with the Factotum's Arcane Dilettante class feature. If I took a word such as Naenkrau, which allows me to leave up to two spell slots unfilled I can add a +1 to all the DC's of all the other spells of that level. The +1 DC affects all your casting (granting my Wizard Spells +1 to their DC's). Can I legitimately use Arcane Dilettante to gain the bonuses off of the Illumain Words?

SLAs aren't spells; they don't react to outside effects like spells do unless the outside effect specifically calls them out on it. Arcane Dilettante only grants SLAs, which follow those standard rules for SLAs; this means it has a few abusable traits like standard action casting times, but it also means that AD doesn't interact with Naenkrau &c. at all.
