I think you'd have to explain a bit more what you're trying to do
and how your function is invoked.

The content of the previous command-line is available in the ":"
register, so you can

function! Foo()
echo @:
endfunction

However, that register is readonly, so you can use the histadd()
function to insert new entries in the command-line history. That
said, you can combine them to do something like

function! Foo()
call histadd(":", substitute(@:, 'old', 'new', 'g'))
endfunction

Alternatively, if you're executing the function in a mapping, the
mapping can just modify the command-line as you see fit.
