Little update about success with placing 2 qcells separated with qe. I managed today to open only 4 colonies today - all have laying queens. In one is 1 queen, in two are 2 queens ( I have now two extra queens to play with), in fourth by observing split colony, below is also queen, but didn't started to lay - any day soon will ( didn't manage actually to see her). I will check and sort the rest when I have more time, will write the result.. So far, the result is nice..
