It was my understanding that the gelatinization temp quoted for wheat is for the pure starch and doesn't hold true for the grain itself. For example, when you add flour to a sauce to thicken it, you need to bring it to a boil to get the starch to thicken (gelatinize) as far as I am aware. This is opposed to pure corn starch, which thickens well below the boil. That said you will get some gelatinization at mash temps, and a bit of starch isnt such a bad thing in a sour beer.
Boiling the wheat isnt too tough. Just grind it and mix it with plenty of water. Using 2-row youd be safe with 30-40% raw wheat.
