I don’t think there is any reason not to try it. Unless it breaches warranty.
But it’s unclear to me what you are after?
If you’re trying to slacken the HA, angle headsets can e an option too.
I would recommend a fork such as DVO Onyx SC, because it can be adjusted from 160mm to 180mm travel without any additional purchases.
I rode a Yeti SB5.5 for years. It had 140mm/160mm. My problem was never the fork travel. Never.
But Yeti’s rather linear suspension design on the other hand, made it necessary to run large volume reducers in the shock. Even then, I would often bottom the rear out.
I know the Leverage curve has been made slightly more progressive for the SB130. But I would still question if a 130mm rear 170mm front would be a balanced setup
