that is what i do, just bring my potted plants indoors and line them up on a south facing window, some remain in totes; from this effort i usually lose about 10% for whatever reason. i preferred that the plants that were going to die, die early but that is never the case, they always wait until spring after a winter of babying then drop. my yellow bhuts did that, around march/april they started to grow nicely then by june, they started to drop their leaves and by mid june both plants were dead - several other plants just died off also. i do trim back some branches just for the sake of making the plant fit easily into a tote or on the window ledge and to not interfere with other plants. i do not trim the roots. as for watering i can usually get away with once every 2 weeks.
previously, i would take my plants and cut back both roots and branches then hibernate the plant in a dark north facing room with only early morning sunlight. i would only water maybe once a month depending on soil moisture. this technique usually had a 50% survival rate for me, so i switch methods, now i have some plants that are several years old.
i do get aphids but more so with my hydro plants, just do to my set up it makes reaching some plants very difficult. i use a mixture of just soapy water, Safers Trounce and another no name bug killer.
at some point i do have to cull the inventory, this allows me to try new things. like right now i am looking at a assam bhut in my hydro system that has dropped most of its leaves and roots are browning - hate like heck to kill it off as it is about 2 years old but....... i have a whole bunch of other varieties that i would like to grow but have no room. things like dundicut, sannam that are 3 years old and take up way too much room and just taste like an ordinary cayenne that i can buy at the grocers.
have fun.
