German style orthography

I am making a language supposedly discovered in the
late 1800's by Germans on an island south of the
island Mafia on the coast of Tanzania. It includes
"whistlized" consonants, where labialization was taken
to such a degree that the w-sound is now a whistle, a
voiced whistle in the case of a voiced "whistlized"
consonant.

The phonemes are:
(plosives)
/p/
/b/
/t/
/d/
/k/
/g/
/q/
(nasals)
/m/
/n/
/N/
(fricatives)
/P/
/B/
/T/
/D/
/s/
/s_m/
/z/
/z_m/
/C/
/j\/
/x/
/X/
/h/
(laterals)
/l/
/L/
(approximate)
/j/
(rhotic)
/rR\)/ (This is a simultaneous r and R\... it is fun
to pronounce.)
(affricatives)
/tT)/
/dD)/
/ts)/
/dz)/
/tC)/
/dj\)/
/kx)/
/qX)/
("whistlized")
/s_m_W/ (_W represents "whistlization")
/z_m_W/
/C_W/
/j\_W/
/x_W/
/t_W/
/d_W/
/k_W/
/g_W/

Vowels are:

/i/
/I/
/e/
/&/
/@/
/u/
/O/
/A/

So, is there any possible way I could fit this into a
German style orthography without so much ambiguity
arising that I couldn't understand a single word of
it?

Er, the name of the language is, by the by, /t_W@s@/
