endermite portal

The endermite portal would be a new portal made with endstone that, unlike the ones we already know, would not take you to any specific dimension, but would have the ability to link different points in all dimensions, thus being able to make transport systems very fast, I could also link random points of the overworld, the nether and the end, but how would it be activated? With a new item, the endermite pearl, the endermite pearl would be an item that would release an endermite when you kill it, only with a 10% probability, well, the endermite pearls would work in the following way: When you right click on a portal frame, the endermite pearl becomes a charged endermite pearl, the charged endermite pearl takes it to any point in any dimension, there you right click on Another endermite portal frame and the charged endermite pearl disappears, then the portal is activated and it is already linked to the portal in which you loaded the endermite pearl, but how do you link two random points of any dimension? Easy, loading and unloading the endermite pearl in the same portal, as anyone can understand, an endermite portal could not be activated, or used, during combat with the dragon, in fact, if there is a dragon they should be disabled until they kill to the dragon (I mean that because if this is the second time you kill the dragon, you could just flee to the overworld or the nether through the endermite portal).
