Author here. To be honest I posted it in the first place to hopefully generate some discussion about whether there might be a better way to do this(!). I think memorising 26 mnemonics is possible (and i disagree with the below commenter who says 124 individual words might be easier...) but perhaps the information can be further compressed.
Can you elaborate on how your method works a little? How are the two lists derived?
Oh sorry, classic case of not realizing not everyone hears your thoughts :-)
For "a", there's a list where "a" is the first letter, and a list where "a" is the second. What I wrote out above is an attempt to show the structure. The letters on the left are possible prefixes for "a", the letters on the right are possible suffixes. Then I stuck "-a-" itself in the middle because that seems like a good visualization.
