There are things you need to consider:
1. Excessive amounts of shop signs in one place degrades fps quite quickly, you want people to go to your shop and not have 10 fps.
2. The shop will be very difficult to keep in stock; it will take Ages to restock some things. Also, there are obvious items that people will basically never buy such as furnaces or what not, which does not make up for the effort of selling it.
3. There will be quite a lot of competition. There are specialty shops that are guaranteed to beat your price since they obviously have the farms or the resources to specialize in selling those items. It's basically assembly line logic, specialists are more efficient than jack of all trades so to speak. If someone invests 100% of their time onvillager farming and you can only invest 25% of you time because you got other things to stock (wood, flowers, etc), they will most likely have a better trading center and lower prices.
In summary I encourage you to specialize. I did too, and earned a fortune selling the cheapest enchanted books on the server (before the reset ....).
Now, of course there has been a couple of successful everything-shops in the past such as Uri's and 7-11 because it offers convenience, but that comes with time and a lot of effort. However it'll be hard to rise to that point if specialized shops become famous. I don't think anyone bought any enchanted book frequently from anyone else after I had set up my book shop before the reset.
Also, if you try to buy them out as a counter-measure, then they're the real winners as they sell out quick since you are buying from them, and you only earn a little bit of difference.
