The standard way to represent /tʃ/ in one letter is "č".
The standard way to represent /tʃ/ in one letter is "č".
For example, in Year 1 that useless letter "c" would be dropped to be replased either by "k" or "s", and likewise "x" would no longer be part of the alphabet.
The only kase in which "c" would be retained would be the "ch" formation, which will be dealt with later.
Year 2 might reform "w" spelling, so that "which" and "one" would take the same konsonant, wile Year 3 might well abolish "y" replasing it with "i" and iear 4 might fiks the "g/j" anomali wonse and for all.
Jenerally, then, the improvement would kontinue iear bai iear with iear 5 doing awai with useless double konsonants, and iears 6-12 or so modifaiing vowlz and the rimeining voist and unvoist konsonants.

Incidentally, there's a reason the IPA for the sound is /tʃ/. It's two sounds pronounced together, in a manner essentially identical to the /kt/ at the end of the word "act", or the /ts/ at the end of the word "cats".
The parallel is not perfect - in particular, affricates are generally understood as being a single sound, while coarticulated stops are generally thought of as being two sounds in sequence, even where they show all the phonological independence you'd expect of a single phoneme. (Compare e.g. Greek "Ctesias".)
