I don't see why not.  
Sweet! 
Cook 1lb bacon (I do mine in the oven, so much easier!)
then 
Throw all together in crockpot: 
1/2-1lb noodles
1 can cream of mushroom soup
5oz mushrooms
cooked bacon
8oz frozen peas (or however much you like, omit if you don't like)
4 oz cream cheese
15oz can chicken broth 
2T garlic powder or 2 minced garlic cloves
Stir just to distribute evenly. Cook in crockpot on high x 30min, then on low x 2-3 hours. 
Terribly lazy cook here.
