The legs are a bit wider on the 22.5 than the 18.5, but since the mounting holes are centered, I assume the wheel brackets would fit.

On my 22.5, I went with a setup using steel angle like the one below. Another advantage of this is that you can easily use the cross-braces to push the WSM around (ie: with a foot) and as a grip when dumping ashes out.
