Consonant Clusters in Boreanesian?

After some translation excercises with Boreanesian, I'm not=20
really satisfied with the way Boreanesian sentences tend to=20
have several syllables. There is already vowel reduction in=20
Boreanesian - or at least I have analyzed it that way. But=20
now I'm wondering if what I'm seeing and hearing is at=20
times in fact CC- clusters instead of C@C- sequences.=20
Consonant clusters would definitely shorten the syllable=20
count in Boreanesian.

For instance, I can easily imagine a CC- clusters like=20
/pl-/ and /km-/. And I have even seen a CC- clusters in=20
Salish like /pp-/ (pronounced as [p_hp-]) and=20
/m<creaky>n<creaky/ (pronounced [?m?n-]). Also, if we look=20
at Khmer, which has a lot of these CC- clusters, some are=20
cited as being clusters with 'a slight vocalization'. For=20
instance, the word /mday/ "mother" has a /md-/ cluster=20
cited as 'separated by a slight vocalization between <m>=20
and <d>'. I understand this as being phonetically [m@d-]=20
rather than strictly a cluster. Similarly, I can't really=20
imagine something like /jj-/ as a cluster if it has a=20
'slight vocalization'. For Khmer, it seems, sequences=20
represented as CC- sequences and sequences represented as=20
C@C- sequences are actually one and the same thing=20
phonemically. This may very well be the case with=20
Boreanesian as well.

My question to the group is, first of all, are there=20
limits to what can become CC- clusters? Secondly, are=20
there any limits to what are considered CC- clusters? It=20
certainly doesn't seem to be the case with Khmer, so I'm=20
curious.=20
