Perhaps try it and see - obviously not with loads of IoB and a massive negative rate of change of BG, but running low gradually should be doable and not overly unpleasant (and very easy to fix if you decide you've had enough).
You may find that if you're running high you get "false hypo" symptoms as you run down into normal BG territory - I generally find I can differentiate this from an actual hypo as I can do mental arithmetic/etc., whereas when hypo it's pretty hard work!
