Probably if you can get them spread out enough. But if you put a bunch of antennas close to each other, they all interact and make RF mud. I recently had up a 20 meter tribander 20 feet below my doublet. I noticed as soon as I hung it there that the doublet wasn't performing well. And as soon as I took it down, the doublet started working again. So, the beam was for 20,15,10 meters, yet it clearly disrupted the doublet on 40 and 80 meters. And hugely on 20 meters. Lesson learned. You can have many antennas, but you need to spread them out or they have an effect on each other and at least half the time it will be in bad ways. A fan dipole is no exception to this except for one thing. After you build it, you tune each segment to resonate even though it is in proximity with other wires. That is essentially negating the detuning effect of the other elements. This is truly a challenge on a multiple station field day setup. I would say that a good horizontal (I prefer a doublet) up as high as you can get it and a good vertical with a great radial field will be an excellent starting point. If takes quite a bit of work to get a better setup than that.
