Re: Can I mix the use of fold-expr with fold-marker just as mixing fold-expr with fold-manual?

No. Because folds with "marker" method are defined by inserting text into the buffer.

Just changing foldmethod does not modify the buffer for you.

You could perhaps script something that would find all fold start/end locations and modify the buffer to insert markers but that would not be trivial and I'm not sure you'd want to have that happen in a code file anyway.
