If you are going to decide that timeout wins are lesser than resignations or checkmates, you're really going to have to also consider the position. How many points for a clearly won position, how many when the game hangs in the balance, how many if objectively losing? But then the same applies to resignations, some people resign for various reasons when ahead, how should those be treated? How could these positions be evaluated? Who would do it? Would positional factors be taken into account (it isn't hard to create a position whereby the side with fewer material resources actually has the better chances of winning.
Also would this make much difference? Players ratings might rise slightly, but then in turn they'll tlose more for defeats, remaining around the same level. Besides, large numbers of us have picked them up from time to time.
The bigger problem, which primarily affects tournaments is what to do with players who suffer large numbers of such timeouts, but there are enough threads about discussing alternative solutions to that one.
