Meaning related to sound

I'd like some input on some things for malat. I'm thinking of making my
vocabulary related slightly to the sound of the words. Here are some ideas
I have come up with so far:

k = any stop (p,b,t,d,k,g)
f = any fricative (f,v,s,z,sh,zh,th,dh,kh,gh)
m = any nasal (m,n,L,ng)

harsh, quick, noisy, strong, etc:
k-k, f-k

flowing, continuous, soft, etc:
f-f, fm-f

neutral words would be either k-f or others.

What do you think of this idea? And one more thing: should words of similar
meaning (like words of possession) all be derived from each other, or
should they be different at a certain point outward (in meaning)?
