aa → aba
bb → bab

It is possible to build sequences in the way where aa, bb and other sources for substitutions are build first in the sequence, for example:

((a a) (b b) (a a))

and to make replacement we just replace all instances of (a a) with (a b a) and all instances of (b b) with (b a b) and we will get:

((a b a) (b a b) (a b a))
