Can I use Knorr vegetable stock cubes in place of Knorr vegetable soup mix in a recipe for spinach dip?

I am making a spinach dip based on a family recipe. The (American) recipe calls for Knorr vegetable soup mix. But where I live, I can only find Knorr vegetable stock cubes. FYI the other ingredients for the dip are sour cream, mayo, water chestnuts, lemon, salt and frozen spinach. Grateful if anyone has any suggestions.
