installing recessed lighting behind fire barrier?

I live in a townhouse, and I would like to install some recessed lighting cans in one particular room. However, my attic crawlspace ends at a fire barrier wall about halfway over the room. Several of my desired can locations would sit on the other side of the barrier wall. If I use "remodel" type cans, I don't need the attic access, however I would still need to run electrical wiring through the firewall (probably through a drilled hole in the joist that supports the wall). Is this a bad, bad idea?

thanks for any advice,

When transitioning a rated partition a common practice is to install a metallic sleeve through which the wires are fed. After securing the conductors on both sides, caulk both sides of the penetration with "fire barrier and then fill the sleeve with the same material. Fire barrier is available from most big box and large hdw. vendors and is a caulking that is fire resistant.
