From America On-Line:

Please advise if you can mix 70/30 insulin and regular insulin in the same syringe for administration.


Yes, you can. We advise that you stick with one brand, however (either Lilly's Humulin or Novo's Novolin) for both the products you're mixing.

70/30 insulin is 70% NPH and 30% Regular; by adding more Regular, you'd be decreasing the percentage of NPH and increasing the % of Regular. You could also do this (and most people do) by mixing NPH and Regular.
