yes, you can easily do what your suggesting, but it will become rather cumbersome rather fast.. that foot and a half monster today is going to turn into a three or four foot monster in about two or so weeks, and wait till it really starts budding and becomes top heave and rather awkward..
it can be done, no doubt, and if its just one plant, it may not be all that difficult.. i know that i like to take my plants into the shower to water them once or so a month, and once they really start to flower hard, it becomes a real chore and i stop doing it after awhile..
