You may not have considered this but....

Splice the two antenna's boom together, in line, with the rear of the 446 
boom connected to the front of the 124WB boom, keeping a 1/4 wavelength from 
the 446 reflector to the 144 last director, and rear mount the combination 
to the main mast.  I have done this before, and it seems to work, although 
you may need to add a Dacron rope strong-back from the 446 antenna to a 
point on the vertical mast above the two booms if the antennas appear to be 
'saggy'. (although both ant's are small)

Just a thought,

Ken W9GA

Correct me if I am wrong, but I would take half of the stacking distance
quoted for each antenna and that would be the capture area. (it's been a
while since I went through this)

56 / 2 = 28
25 / 2 = 12.5

So in theory I would need 40.5" of separation?
