I suspect that the methods suggested in the earlier thread are the only ones easily available.
I have been looking around for these conversion bushes but AG seem to be the only source. The combination of metric and imperial is not very popular. I suspect AG introduced them as a way of avoiding having to produce new molds for the driving wheels when some manufacturers introduced 2mm axles.
The only other way is to ream out the axle hole to fit a larger outside diameter bush but that implies having those tools
I will be ordering a quantity for the stores but delivery will be some months away
