One reliable approach can be to ensure the gear attachment bolts shear off, leaving one with an intact landing gear and fuse (in the aft direction not vertical). Works best with low wings. The local Ag aircraft have this feature and not leave the occasional leg on a hillside, with a legless landing resulting in only an aileron change.Gear on bush planes is normally ripped off from hitting stumps and snow berms. I repaired a Citabria that hit a snow berm on skis. It's much more difficult to repair the fuselage (especially in the bush) than replace a bent gear.
So making the gear stronger than the fuselage might not be optimal. (as winginit said)
