Hello Acorn,

I do think your approach is useful for most people. If there is need for more shortcuts, there is Wincompose (https://github.com/samhocevar/wincompose) that gives the possibility of custom shortcuts (and has a humongous set of default shortcuts). Personally, I find that its default shortcuts are a bit too much. However, the program can be totally customized by removing the check marks in Options, Composing, Sequences, and defining your own user-defined sequences in the .XCompose text file. The result can be very similar to AllChars which was a much used utility in older versions of Windows.
