Film's a classic in my books and should not be messed with lightly.
I would actually welcome a new Robocop film (which I believe has been confirmed as it's own continuity, separate to that of the existing films).
I'm actually confused now, I wouldn't mind seeing a new Robocop film but am quite opposed to a Total Recall one. I don't know why but I seem to think it's less likely they could balls up a Robocop re-imagining than a Total Recall one.
