The distance between those two antennas will determine how directional the are. Larger separations make for more directionality than less separation. Something on the order of about 1/4 wave length separation is thought of as the minimum distance for practical use. shorter separation distances are certainly possible, just not very usable for a directional antenna system (the only thing those dual antennas are good for).
Would they work if you only have something like 60 - 65 inches separation? Yes, but not as well as if they were further apart. Would it be worth doing? I can only speak for myself, and since I don't see any practical use for dual antennas at all, I'm not too sure you want my answer to that. You decide for yourself.

Oh, running the power you are talking about is just going to make it even more 'fun'! Lots of voltage involved with the type of impedance matching you're talking about doing, start looking for some RG-9, at least, doubt if RG-59 will work very well. Have fun.
