Remove ore dictionary? I think you are barking up the wrong tree here. ore dictionary isn't a part of the problem, in fact, it is a part of the solution.
In order to do what you want you need to do 2 tings.
One: disable the ore spawning in the configs of most mods, and instead use a single mod to spawn the ores.
Personally I use Cofh world to spawn ores. It can be used to spawn ores from any mod.
Two: use MineTweaker and Modtweaker to change the recipes that have nuggets/dusts/ingots/storage-blocks as output.
This is where the ore dictionary comes in handy. Just remove the recipes that output the ore dictionaried nuggets/dusts/ingots/storage-blocks. Then add them back with your specified preferred output.
See attached file:
I created this scrip for myself, it works for my personal assembly of mods. It probably needs to be changed to work well with your setup, but it can be used as a starting point so it will save you some work.
If you change anything, please fill in you own name at line number 5 and 6 but keep line 3 and 4 intact.
Note: Don't forget you need to change the file-extension from ".txt" to ".zs"
