if I have to use multiple adjectives in English... I'll use them in whatever order I want... I didn't even realize there was a set order to what type you had to use when
but if it didn't sound right, I'd probably just nominalize them...
for example:
the green little fast cat
the fast little green cat
the little green fast cat
technically these seem to imply different things
"the little "fast cat" which is green"
"the fast, little "green cat" "
"the little, but 'green' "fast cat" "
this last one is kind of similar to the first one, in these cases one could use a pun on 'green' to imply that the cat is also somewhat inexperienced
but if you're really bothered about the specifics, you could easily say something like
the little "green cat" of much quickness or something like that I guess
