Get one now. If it works, great. Worst case you trade more memory for slightly slower memory until you upgrade the other one. I'd give it a shot.
If worried you could dig through their docs for any references to interleaved or dual-channel memory access. Almost all dual-channel capable systems work fine with unequal memory installed, just slightly (very slightly) slower. The additional memory will more than make up the difference unless you run lots of memory transfer benchmarks.
