Hey brother blackbird, judging from the knowledge you have dropped on us here at destee.com, I would have bet you were already an Egungun medium. Anyways, The first thing is, if you are feeling it, then you need to ask the oracle the question, "Does it bring me ire (good fortune) to receive Egun?"
There is alot of confusion regarding your question, for one, because in the Diaspora for some reason we have separated Orisa reverence from Egun reverence. Also, in the Diaspora usually when people are working with Egun they are actually only working with one ancestor, which in Yorubaland is called ara orun. The Ifa concept of Egun is that Egun is a collective spirit made up of the collective experiences of all those who have come before us in our family lineage.
The thing is, the idea of "crowning your head" is a western idea. so the answer to your question is no. However, one recieves Egun in the same way one recieves Orisa so the answer to your question is yes. Let me try to explain. First of all, to "crown" someone refers to the Yoruba word for crown, "ade" as seen in awo Sekhemu's avatar. Only Oba (kings) recieve ade. So then linguistically the idea of crowning regarding initiation in Egun, Orisa or Ifa is wrong. In the west the idea of crowning comes from the belief that initiation involves putting the ase in the person's head, which is totally wrong. EVERY INDIVIDUAL ORI CONTAINS EVERY ODU. ORISA, IFA AND EGUN ALL ARE BORN OF SPECIFIC ODU, SO EVERYONE IS BORN WITH ALL THAT EXISTS ALREADY IN THERE ORI. ALL INITIATION DOES IS UNLOCK LATENT POTENTIAL. Nobody puts nothing nowhere. Nobody is "crowned," nobody is "given" ase.
Now, if your question is does Egungun initiation unlock the potential for communication with the ancestors by unlocking latent potential, the answer to your question is yes.
