"In Modern Greek, it has two distinct pronunciations: In front of high or front vowels (/e/ or /i/) it is pronounced as a voiceless palatal fricative [ç], as in German ich or like some pronunciations of "h" in English words like hew and human. In front of low or back vowels (/a/, /o/ or /u/) and consonants, it is pronounced as a voiceless velar fricative ([x]), as in German ach or Spanish j. This distinction corresponds to the ich-Laut and ach-Laut of German."
You could claim it if you'd speak Bavarian (Chiemsee starts with a "k", for "Chemie" people are diveded if it's "kehmee" or "shehmee").
So don't use weirdly constructed things as names with your own pronunciation instruction. That's a tragedeigh.
Ich and Chemie are pretty similarly pronounced (some people say either with a harder k sound, ik, "kehmee"). Chemie also derives from the Greek χύμεία, so it contains the Chi to make the comparison.
A similar case can also be made for Jesus Christus, I certainly think Christus' pronunciation starts like crust.
And hey, if you derive the Greek root for it, you get Χριστός, which starts with Chi again.
I think a better case can be made just arguing against mixing alphabets like this.
