K1 Series CFS Upgrade Accessory Kit

I have a CrealityK1 3D printer. EarIier this year I replace its hot end with the K1 Series Ceramic Heating Block Kit - Quick-swap Nozzle Kit. I now need to replace the K1’s extruder. As I eventually want to purchase the CFS, I was wondering if I can install CFS Upgrade Accessories Kit to replace the extruder with the new Extruder with integrated cutter and runout sensor (rather than the standard K1 Extrusion Kit), but continue to use just a single spool input until I can afford to purchase the CFS later in the year?

Kind regards,
