Hi, Entrpy53, and welcome to SGL.
I can't give you specific advice to your question, but aperture can help cut through light pollution to some extent. But nothing beats being able to get a scope under a dark sky. I don't know how "mobile" you are and if getting away from the city is a possibility for you. But, if it is, I would definitely factor that into your upgrade. You will be able to purchase a bigger dobsonian for a similar sum compared to the 130mm. [Yes, I hate it as well when someone comes along and tells me to consider a different purchase than the one I have decided upon!]
Another thing to consider is that, whilst adding extras may seem a cheap way of getting extra kit, every piece of glass you add to the system (like reducers) reduce the quality of what you are seeing to some extent.
The only other thing I can recommend is that you go for one scope (only) first. Decide where your main passion lies (planets & moon or deep sky objects) and get the one best suited to that. Then, when you have experience with that one, you will be in a better position to decide how to extend your kit.
Enjoy the journey.
