If weight is a concern just flute the barrel
Or a thinner contour or both.

If you want to use most of the 100-107 gr bullets you will need a 1 in 8 twist. As for length for a 6mmAI I'd opt for 28". I have a 28" 257 weatherby and that barrel added velocity without being too long for me. Get the barrel long, you can always cut some off and recrown if you find it objectionable.

Weight isn't really a concern. I have lighter guns if I need them, but I'm also not TRYING to build the heaviest gun I can haha. If a 22'' gun will shoot the same as a 26'' gun, then I have no problem reducing the length and weight of the barrel.
