Rumble passthru on wiimote extentions?

[Joelgp83]

So I'd recently picked up off of amazon a pair of wiimote extentions that offer a gamecube controller port, such that I can plug the controllers into it to allow the wiimote to effectively BT connect GC controller to the wii / Nintendont. Internally it presents to the system as a Classic Controller in terms of mapping, but what I'm wondering is if its possible for the wiimote pass thru rumble commands to the GC controller.

Rumble events are properly being sent and reacted to by the wiimote itself, so I know that's working, but I have no idea if its possible for those events to to be sent "down the chain" to the GC controller, and if this is so, can Nintendont support this?

Because while I like the ability to use the GC controllers wireless, it DOES feel a little weird without the rumble, lol.
