The old reservoir patches couldn't be cut but they have been matrix patches for many years now which are well suited to cutting as it allows a customisable dose.
It is just trickier when using sequential patches as not every patch is the same, so you will need to find 7 extra estradiol patches and 7 extra combined patches and do one and a half estradiol for 14 days then one and a half combined for the next 14 days.
There are actually far better options than this unless norethisterone is the only progestin you tolerate.
Also is there a reason you feel you need to spend every 4th week bleeding, because if you are close to or past menopause, you could either use the continuous combined patches which at least are all identical if cutting them, or if not then there are other oral progestins that could have you bleed free regardless of menopause stage, alongside a 75mcg patch that you wouldn't have to mess about with.
