You can make Vim do almost everything. WHat exactly are you looking for?
i_<c-y> : copy character from line above. So you can use this to write
you second line
<c-x> l : line completion: you can use this to get the same line quickly
then changing what is different.

How should it behave? If you can't describe it you can't implement it.
Of course you can write a script which get's this part:
> .* {printf("yada yada \n");} //regex2
^^^^^^^^^^^^^^^^^^^^^^^^^
and allows you to complete against them. (:h line(), getline()
Also :h compl-func -> examples
However you can consider using a plugin such as snipMate to insert
templates such as:
$regex {printf("$string");} // regex$N
last but not least in this case you can do
yy (yank the current line)
20p (paste it 20 times)
and start editing (this is very fast for most use cases)
where cursor is placed at $.
So refine your wish, please.
