replacing downlights with a central rose fitting?

We want to replace our 4 downlights with a central rose fitting in the future. We are planning on laying a floor in the room upstairs, so access from above will not be possible at a later date. Would it be possible to have the wiring done now, with a rose fitting, but not connected,, which could be used when we are ready to buy a fitting, therefore not needing access from above or having to do any major work.
