I usually move the original colony away and place the queenless split in it's place, the original should have the resources to recover better than the queenless would have without the foragers. The queenless split will now have all the foragers to build up with and both should do fine. I usually just do equal splits with two of the same size boxes but a five frame should do as well or better than my method.
As for drawing comb I find that feeding a weak solution of 1 part sugar to two parts water during the dearth will cause them to draw comb better than a strong solution, in fact I feed mine the weak solution all during our two to two and a half month dearth, holds down robbing and causes them to build up for the winter. I do splits a good bit this time of year.
