Sesamic languages

Should i have Finnish-like gradation patterns in my new Quame branch?
yes!!!!!
that would be great
that could be open sesame
basically:
plosives lenite conditioned by syllable openness
pp > p > b
yes, b > w, d, g > j (spanish style)
k > g
pp > p > b > w
tt > t > d > 0
cc > c > z
ƛƛ > ƛ > λ > j
kk > k > g > j
qq > q > ɢ/ʀ
yes
k becomes c
or ch?
kw > k
qw, q > q
so if k becomes c, then c>z or g?
unless g>z
g > z too
will you have z leniting to j?
yes
λ > 0
but z !> 0
z > 0 or j
z from *z letnies to 0
while z from *g lenites to j
yes
unpredictable gradation grin emoticon
ł -> ?
also ł?
yes
this proto-language could be open sesame
