The South Koreans coincidentally used some type 99s that were rechambered to 30-06. Some of these conversions, I've read, were done by US armorers.

During the Korean War, approximately 126,500 short and 6650 long Type 99 Rifles were re-chambered under American supervision at the Tokyo arsenal to fire the then-standard .30-06 Springfield cartridge. "Apparently" intended for the South Korean gendarmerie, few rifles appear to have been issued at the end of the war in 1953. These rifles were fitted with a lengthened magazine well and had a small notch cut in the top of the receiver to accommodate the .30-06 round's 1/3 inch greater length.[3] Accuracy suffered, due to the difference in cartridges, rifling rate and characteristics, but they were nonetheless functional. Conversions to both .30-06 and 7.62 NATO have also been performed by civilians, often along with sporterising modifications.

I don't want to say I told you so, but

With all that work you might be better off just having it rebarreled to .308?
Or find some .30-06 loads with a short OAL, I think there was a ‘lite’ loading that had a 125gr bullet for a while.

I had a Type 99 that was rechambered as well. It fed .30-06 just fine out of the magazine. Accuracy was very poor, bullets weren’t stabilizing. I considered reloading with .312 bullets but in the end give. How bad the triggers on these are I eventually sold it.

Nice gun other than the trigger. Loved the sights.

The Type 99 sports a basic Mil Mauser trigger config. Easily made smooth and crisp with a bit of spring changing, and judicious stoning.
