Binding not-nested components

Hello i have the following problem:
I have a Component A that exposes some Inputs and some Outputs.This component has a nested B component inside it.
The B component also has a C component nested inside.
I want to know if there is another way of communication (sync-ing or binding ) between A and C without passing through B.
ComponentA
bindToCSomehow:number;
@Input()
inputFromC:number;
<componentB></componentB>
<p>{{inputFromC}}</p>
<p [emitterFromC]="doSomething($eventFromC)"></p>
ComponentB
<componentC></componentC>
ComponentC
fromA:number; //somehow i need this bound from A
@Output()
emitterFromC:EventEmitter=new EventEmitter();
onClick():void{
this.emitterFromC.emit(true);
}
<button (click)="onClick()"></button>
<p>{{fromA}}</p>
Is there any way of making A and C communicate without having to map all inputs/outputs from both sides inside B?I do not want B to be the mediator.I need a fast reliable way of syncing the two of them.
I was thinking of using a service to pass data between them ..but i fear that it would have a big overhead.
P.S I simplified the scenario a bit..my data structure is a JSON so my components would like like this:
<ComponentA> <---|
<COmponentB> |
<COmponentC> | How do i link these two efficiently ?
<ComponentC> |
.............. |
<ComponentC> // <---|
