I was thinking of the DRBG implementation: decouple it from the underlying 

ciphers. Though, I am not fully sure that will work as there are several 
specific settings that depend on the underlying ciphers (e.g. the state of a 
Hash DRBG with SHA-256 is 444 bits whereas a Hash DRBG with SHA-512 has 888 
bits).

The only reason DRBG is in crypto is because it implements stdrng.
