Zsh alias extension

Is it possible to configure zsh to expand global aliases during tab completion? For example, I have common aliases:

alias -g '...'='../..'
alias -g '....'='../../..'

but when I type, for example cd .../some<tab>, it will not expand to cd .../somethingor cd ../../something. Therefore, I often will not use these convenient aliases, because they are incompatible with tab completion.

I am a user of Michael Magnusson rationalise-dot. From my zshrc:

# This was written entirely by Mikael Magnusson (Mikachu)
# Basically type '...' to get '../..' with successive . adding /..
function rationalise-dot {
    local MATCH # keep the regex match from leaking to the environment
    if [[ $LBUFFER =~ '(^|/| |      |'$'\n''|\||;|&)\.\.$' ]]; then
      LBUFFER+=/
      zle self-insert
      zle self-insert
    else
      zle self-insert
    fi
}
zle -N rationalise-dot
bindkey . rationalise-dot
# without this, typing a . aborts incremental history search
bindkey -M isearch . self-insert
