That's what I did.
You COULD just wrap them in tape, but then you're counting on the tape to stay on over time and that's a risk I wouldn't take compared to a $.05 wire nut. Twist a small one on each wire, then wrap it in electrical tape so it's secure. Then still move them far apart. In can make a cheap spacer out of a piece of cardboard with some holes poked in it and the wires fed through the holes. No telling when a critter will be wandering through your ceiling looking for a snack.
Yeah, probably overkill but it's a very cheap way to remove risk.
