Chickpea cooking water as stock for soup?

I make a great Spanish ham-chorizo-chickpea-garlic-onion-spinach-tomato-mild paprika soup. The recipe says to use chicken stock as the stock. However.  I have a vat of chickpea cooking water staring at me from batch cooking for the freezer. Will I destroy all the other lovely ingredients and produce some kind of watery swill if I use the chickpea water, or will it be fine?

It will be OK (and probs preferable to using a chicken stock cube) but it won't taste anything like as good as it would if made with a proper home made chicken stock.  There is no depth of flavour in chickpea. 

Donny Darko was right. It was fine but it wasn't the magical integration and heightening of all the influences that occurs with chicken stock. I might do it again but for a soup that will tolerate it better.
