As far as why I don't want to move to and HID kit--just because of all the other issues it could introduce--other relays, water issues, modifying the factory parts, etc. None of these mods are tested for 10yr service life like the rest of the car. (One of the reasons I am open to the idea a factory HID swap.)
I'm going to call PIAA and see what they can advise. I want to use their H3s in the fogs anyways.
High quality HID kits are really not problematic like you make them sound. Honestly, they are not like the ebay crap for $35. Retailers like TRS discuss this rather bluntly. They explicitly state that even their bulbs alone cost more than entire kits on ebay but there's a reason for that: quality. They back up that quality with a long warranty that is unrivaled.
The relays are not necessary in every HID kit, but are a component of Morimoto kits which actually make them superior. The relay resolves flickering issues seen with lower grade kits because the relay draws power directly from the battery. Water issues are almost non-existent. HID kits are famously waterproof. Some retailers even demonstrate by dunking their HID kits in water tanks and operating it. See the picture below.
Halogens on the other hand?

They burst on contact with water.
HID kit installations are also 100% reversible and I've personally gone back to halogens in my old Mazda when my ballast failed. When the company gave me a new one under warranty, I re-installed the HID kit.
While yes, these aftermarket components are not tested for 10 years, guess what? Neither are OEM. Otherwise, ALL companies would offer bumper to bumper 10 year warranties. However, the industry average is only 3 years/36,000 miles for bumper to bumper which covers components like HID systems. In fact, it's not uncommon to see factory HIDs that are out on cars over 7 years old. This coincides with the average lifetime of even factory HID bulbs. Also keep in mind that TRS offers a 5 year warranty (for 35W systems) on all their components if you buy a full kit. This is actually
better than a factory warranty on an OEM HID.
Let's not forget the incomparable difference in performance versus any halogen, even the best. Also, as you know, the Kizashi requires the bumper and headlights to come off to change the bulbs. Given all that trouble, wouldn't you want to avoid doing that more frequently? It also happens to be most of the work going into installing a HID kit. If there is any car I can think of to put in a HID kit, it would be the Kizashi given its difficult bulb change process and factory low beam projectors. To me, HIDs and the Kizashi are a good match.
Lastly, bulbs from PIAA are good, but no rival to HID in either performance or lifespan. Trust me that my HID fog bulbs from Morimoto will outperform PIAA halogens in just about every regard. I also only paid $20 for them (just the bulbs). PIAAs are famously overpriced.
High end halogens like top tier PIAAs can cost nearly $80 for a set which is about half the price of a HID kit from Morimoto. Then consider that high output halogen bulbs have a lifespan of only a few hundred hours. In comparison, HIDs are in the thousands of hours all while consuming less power, giving off less heat, and outputting 2~3 times the light in lumens.
To me, there is no way halogens win in the equation.
