If you have ceiling joist at 24" and your can is in the middle I am not sure that the cables are long enough to reach and then there would be the accessibility issue afterwards.

in a finished surface shall be rigidly secured thereto by clamps, anchors, or fittings identified for the application.

410.30(A) General. Luminaires and lampholders shall be securely supported.
