makam notation

[Andreas von Heydwolff]

Hello all,

being new to lilypond I am happy and thankful with and for its 
possibilites.

A question arose: Is it possible to create the Turkish/Arabic makam 
keys?. There are many keys and the alterations are multifold. Is it 
somehow possible to insert at the beginning of a line alteration signs 
as displayed in the example:

At http://www.neyzen.com/nota_arsivi.htm you can see all the existing 
keys that sometimes require special notations with one or more "b" and 
"#" in the key.

And would it be possible to mirror a "b" or create #/signs with more 
than two lines in it (see also http://www.farzadweb.com/turkishnotes.htm)

If not, how does one suggest this to the creators of Lilypond?

Greetings,
