No, please do not do any such thing.  Please keep *Completions* separate.  Do
not mix such "suggestions" or past inputs with completion candidates.

Simply adding the default value(s) to the history is enough, provided you also
do what is done in Icicles: provide a minibuffer key (available always, not just
during completion) that lets you complete against the history list.  I use `M-o'
for this (by default).

You can pull any number of history elements into the same minibuffer input you
are composing, any number of times.  And you can use completion to access the
history elements.  (And they are kept separate from the completion candidates of
the parent minibuffer - you are completing only against history elements.)

If you want to move beyond the existing M-n, M-p, M-s, M-r for vanilla Emacs,
then please consider using an enhancement like the Icicles M-o.
