Here's a rough sketch of an early stage of Lune^, I'd welcome comments,
critiques, etc.

Provisional phonology
A = /A/
A` = /a/
B = /v/
Bb = /b/ (only in borrowings)
C = /tS/
D = /z/ < /D/
Dd = /d/
E = /e/
E` = /E/
F = /f/
G = /G/
Gg = /g/
I = /i/
J = /x/ or /h/
  {h} is sometimes used instead of {j}
K = /k/
  Note: may make {c} = /k/, and {ch} = /tS/
L = /l/
M = /m/
N = /n/
N~ = /nj/, /J/ also exists in a few conservative dialects
O = /o/
O` = /O/
P = /p/
R = /r/, trilled r
S = /s/
T = /t/
U = /u/
W = /w/
Y = [j\] intervocalically or word-initially (later merged with /zj/ as
/Z/), [j] elsewhere
When a vowel with a grave is stressed, the grave is replaced by
circumflex, as in the name Lune^

No gender
Definite article: invariant _la_ (or perhaps I should stick with _e`l_?
I was considering that Esperanto was an influence, presumably they'd
associate _la_ with their own _la_?)
Pluralization: Sound changes
a -> a`
e -> e`
o -> o`
Consonant-stems add e` (/E/), and change the vowels the reverse of the
preceding, e.g.:
nasyo^n -> nasyone`, but perhaps the singular's vowel should be
preserved, thus
nasyo^n -> nasyo^ne`
Accusative marked with preposition _a_ (extended use of "personal a")
Dative indicated by _pa_ (from the colloquial pa', i.e., para, "for")

No agreement?  Possibly number agreement, undecided

Infinitive/Present: -a, -e (infinitive lost, taken over by present)
Past participle: -ao, -io (-io is pronounced as two vowels, /'i.o/)
Present participle: -ano, -yeno
Future: Ba (/vA/) + infinitive
Past: a + past participle
Perfects formed from verb _a_ (<haber) + past participle
Progressives formed from verb _e`ta'_ (<esta') + present participle
Passive formed from verb _e`ta'_ + past participle
As you can see, future and past inflections were lost, and were taken
over by the _ir a_ and present perfect constructions respectively.
_ser_ was lost
All forms of _e`ta'_ sometimes lose first syllable (i.e., 'ta, 'tao,
'tano instead of e`ta', e`tao, e`tano).
Note: epenthetic _j-_ added to verbs beginning with _a_ when preceded by
ba, a, or e`ta', thus:
yo ba j-ama (remember {j} = /h/) = I will love
Yo ba j-a j-amao = I will have loved, also added to accusative particle
_a_, when following an -a verb thus:
yo ba j-ama j-a Wanita = I will love Juanita
