Zompist Bboard Again

What if you took a word, any word, and subjected it to a series of more-or-less random sound changes (a la the word evolution game), but you could only apply sound changes attested in one specific language family?

I give you, Stickstoff, the German word for nitrogen. Do science to it, but only use sound changes that have happened to some Romance language at some time in the last two thousand years.

I'll go first: initial sC or SC clusters get an epenthetic initial vowel (source: Western Vulgar Latin).
/StIkstOf/ > /EStikstOf/

1. /ʃ/ → /x/ → /h/ (Spanish)
2. ɔ → y / _ [+labial] (Old Provençal, northwestern dialects)
3. /f/ → /h/ (Old Provençal, Béarn dialect)
4. /h/ → ∅ / {#,C} _ (Sardinian)
5. /k/ → /j/ / V_tV (Romanian)

/ˈtɪjtyh/

Sound changes do not a Romance language make…

1. /jt/ > /tʃ/ (Spanish)
2. /tʃ/ > /ts/ (Western Romance)
3. /ts/ > /θ/ > /f/ (Savoyard Francoprovençal)
4. /ɪ/ > /e/ (Sardinian)
5. /e/ > /œ/ (Landes Occitan)
6. coda /h/ > lax vowel (eastern Andalusian Spanish)

/ˈtœfʏ/

This makes our normal word evolution game seem sane in comparison.

Well, my idea was to apply one or two changes per person, building on what the previous person did. But however people want to play, that's fine by me.
