Is it possible...

The amp might handle 1ohm.. it depends on a lot of factors.. what amp, what sub, and what box ??
Generally if you set the gains properly you should be OK.. (that might mean you are actually getting less then rated power)
your other option is to just use one voice coil at 2ohms.. thermal power handling of the sub will be reduced by a bit, but if it can handle much more power then the amp will make you should be OK..
The only other option barring the purchase of a different sub or a recone (and I think this is the answer you are looking for) is to use a power transformer to either reduce or increase the voltage into 1 or 4ohms..

Sure, you can add a resistor in series with your subs, but it'd have to be able to handle whatever half the max output of the amp is. A pile of 10 or 20 watt resistors in parallel will be needed.
Adding 1 ohm of resistance in series with your subs will bring the total load up to 2 ohms. Unfortunately, only half the power of the amp, will be used to drive the subs, the other half will heat the resistor. If it's 100 watts, it'll get as hot as a 100 watt light bulb.
Since the amp will put out a bit more than 1/2 its power into 4 ohms, than 2, you'd be better off just running your dual 4's at 4 ohms. Unless the amp can handle 1 Ohm.
Perhaps tho a smaller value of resistance (maybe like a 1/4 ohm) in series with the subs could raise the impedance enough to stabilize the amp, and still yield a bit more power, but the difference? well you'd have to try it.
I do remember reading somewhere that adding a small resistor in series with a sub, can sometimes improve the sound....can't really remember why. Believe it was in an article about Zobel filters.
Another option if you have the room, would be to buy a third dual 4 sub, and run at 2.6 ohms.
