Hello Rez, you can certainly repot and add soil in the manner you described..but I would delay it to Spring. Lots of finer roots gets damaged, and needs time to dry up a bit and heal. Sometimes you got to consider as well timing when you do that, if it is active growing period of the plant or if the ambient conditions (amount of light, temperature levels) that it likes to grow in is more consistent, otherwise you end up with a very stressed plant and you tend to kill the plant with too much love thinking it needs more water when it actually needs to acclimate and adjust again in its new set-up. And typically I find mid-Spring to be their best period to do so, renewed vigor with longer light duration, temps getting warmer and more stable.
