For me, said by several above in various guises, the only 'change' required is changing the axles - giving the AB's more to purchase onto, and align correctly - whether the end is serrated, threaded or just plain, it'll stay as required.
If the bogie sides are attached after insertion of the axles, this may be a limiting factor, but perhaps not - for me, I'd be talking about adding ~1.5mm to each end - 3mm total - of the axles.
