I did that on a product as well. It went pretty well. The issue is with more complicated UI. The more complicated it is, the faster JQuery breaks down. That being said, it's better to have a bit of a spaghetti JQuery than to try and retrain unwilling programmers in Angular.
jQuery doesn't have to be spaghetti though. It gets that rap I think because most people that used it weren't good/experienced enough to organize bigger code. It can/usually does turn into a mess though but is faster to bang small things out in for me anyway.
On simpler projects, JQuery is more productive. But my main point is to program where it is comfortable and practical. The better academic choice is not necessarily the better choice. View your programming resources as people and make the pragmatic choice.
