Holy shit thats a big ass syllable! I think that syllable structure went to McDonalds too many times and grew!
Only about 31% of the languages in WALS.info's database for which syllable-structure is recorded, have syllables more complicated than (C)(C)V(C).
I couldn't find any five-or-more-consonant onset-clusters nor any five-or-more-consonant coda-clusters.
TTBOMK the maximal syllable structures are CCCCVCCC and CCCVCCCC. (Except apparently some linguists say Wichita has CCCCVCCCC. And maybe the French Wikipedia says Polish does, but I've also read that Polish's structure is (C)(C)V(C)(C) for monosyllabic words, (C)(C)V(C) for first syllables, (C)V(C)(C) for last syllables, and (C)V(C) for internal syllables.)
I believe CCCVCCC is rare.
In fact I think tautosyllabic three-or-more-consonant clusters are rare. That is, I think three-or-more-consonant onset-clusters are rare, and I think three-or-more-consonant coda-clusters are also rare.

You're likely to have a rule requiring rising sonority in onset-clusters and falling sonority in coda-clusters. If you don't have over 5 sonority-classes of consonant phonemes, then such a rule would limit tautosyllabic consonant-clusters (i.e. clusters of consonants in the same syllable) to 5; or whatever your number of sonority-classes of consonants is.
Here are some definitions that some linguists follow. There are alternates, but these are the ones I like, and the ones that I think are relevant to this thread.
A syllable nucleus
either is the first phoneme of the word or is more sonorous than the preceding phoneme, and is either the last phoneme of the word or is more sonorous than the next phoneme. (So if a word has only one phoneme, that phoneme is a syllable and is the nucleus of that syllable.)
A syllable onset begins
either at the first phoneme of the word if it is less sonorous than the next phoneme, or begins with a sonority-trough
-- a phoneme that is less sonorous than the preceding phoneme and also less sonorous than the next following phoneme. A syllable onset ends
just before the next syllable-nucleus.
A syllable coda ends
either at the last phoneme of the word if it is less sonorous than the preceding phoneme, or ends just before a sonority-trough
, that is, just before the next syllable-onset. A syllable coda begins
just after the preceding syllable-nucleus.
By these definitions, every syllable has a nucleus.
Also, if you have a string of consonants ...C1
... where C2
is more sonorous than both C1
, then C2
must be a syllable nucleus.
If you want to use these definitions, you will have an implied rule, if not an explicit one, that sonority can never decrease in an onset and can never increase in a coda.
Given a consonant string ...C1
If the sonority is rising all along, that is, C1
, then C1
are part of an onset; whether or not C3
is also part of the onset, or is instead the nucleus, depends on whether a sound comes after C3
, and which sound does if any.
If the sonority is falling all along, that is, C1
, then C2
is, or is part of, a coda. C1
may be part of the same coda if it's preceded by a more-sonorous sound; otherwise C1
is a nucleus. C3
may be part of the same coda if it's the word's last sound, or it's followed by a less-sonorous sound; otherwise C3
begins the onset of the next syllable.
is a sonority-peak, that is, C1
, then C2
is a syllable nucleus, and C1
is, or is part of, that syllable's onset. C3
is that syllable's coda if it's the word's last sound; it's part of that syllable's coda if it's followed by a less-sonorous sound; and it is or is part of the onset of the next syllable if it's followed by a more-sonorous sound.
is a sonority-trough, that is, C1
, then C2
is a syllable onset or is the beginning of a syllable onset. C1
may be the nucleus of the preceding syllable if it is not preceded by a more-sonorous sound; otherwise it may be the coda of the preceding syllable, or the last sound of that coda. C3
may be the syllable nucleus of the syllable C2
is the onset of, if it is not followed by a more-sonorous sound; otherwise, it may be another part of the onset-cluster C2
These things being so (if they are), I think most of your very-long consonant-clusters will break up into more than one syllable.
If that's not what happens, then, you'll need to explain why you analyze those long clusters as onsets.
