I'm bored at work so I went and actually found you some real numbers.
A 4WD CRV weighs in just over 3,200 lbs. A LX Sedan weighs in at just under 2,500. So we have a 700 pound difference. Well one has a D16, the other has a B20. Conservatively, moving from a D to a B is about 100lb difference. Now your LX weights 2,600. Not to mention the 4WD system. The difference between a 2WD and 4WD CRV are about 100lbs. So that is roughly what the system weighs. Your LX is now 2,700. You're adding a hatch, 250lbs. 2,950lb LX. There is still nothing to bolt that 4WD system to. You have to add support and strengthen the back of the LX. That is going to add weight. You want to use the CRV suspension. That is going to add weight. You want to add a skid plate, more weight.
As I said before, after you modify it, there will be negliable differences in the curb weight of the vehicles. And the B20 was thought to be under powered to move 3,200lbs.
