I would of course, but expect during the contact for the ponies and other races onboard to be immune to the effects of the sirens. Generally during diplomatic contact there is a Archmage there, and Archmages are some of the best when it comes to magic. There is a telepathic branch of magic and it can also be used to resist telepathic suggestion, which is what the Sirens ability is. This is mainly due and part that the Equestrians are paranoid about security and just general rules of first contact.

Sirens abilities aren't telepathic in nature at all, actually. Its a visual-based neurological hack, not psionics. Any commands issued need to be issued verbally.
