Maybe you should try switching to zsh: its zle (z line editor) is highly
configurable. Though it does not have an equivalent to `noremap', you could
bind
keys to functions: your example could be written like that:
function _-ins-aa() { LBUFFER+=aa }
zle -N ins-aa _-ins-aa
bindkey a ins-aa
Not as obvious as `noremap a aa' (or `bindkey -s a aa' that results in ``zsh:
string inserting another one too many times'' error), but it works.
It also has a vi mode and I saw an answer on stackoverflow that explains how to
change prompt when switching from/to `normal' mode:

this question are also useful). It looks like bash does not have such option.
