I think it is suggestive of a pair cipher encoding vowel-less text (with the
vowel-like half typically preceding the non-vowel-like half, to confuse the
issue).

I have some trouble understanding this. Do you mean (i'm improvising as I go
along):

Cleartext:
I see a blue sky with big white clouds through my window

Step 1: remove vowels
s bl sk wth bg wht clds thrgh m wndw

Step 2: split in pairs ingnoring the spaces
sb ls kw th bg wh tc ld st hr gh mw nd w
(this already looks pretty undecipherable to me :-)

Step 3: encode by looking up each pair up in a 26*26 table / codebook
38 228 253 160 14 184 60 48  380 144 28 299 56 621
(using longer and less obvious code-words than I am using here)
(or using roman numerals)

Step 4: encode the reulting text using a substitution cypher
ch bbh bec afA ad ahd fA dh chA add bh bii ef fba

Step 5: add some special characters to signify change from length 2 to 3 and
back again
chEbbhbecafAOadEahdOfAdhEchAaddObhEbiiOefEfba

Step 6: add some random spaces
chEb bh becafA OadE ahdOfAd hEchAad dObh Ebii Oef Efba

We get a low entropy text with a lot of repetition and possibly even a lot
of anagrams.

Greetings, Petr
