No problem at all, Tom. In general, with radials on/in the ground, more 
and longer is better, but neither is critical. 

You could also probably feed both verticals from the same coax if they 
each resonant on their respective bands. They will act just like a fan 
dipole -- that is, the power will go to the resonant antenna, with very 
little de-tuning by the other antenna. I plan to do that here once I get a 
few more rigging points in trees.
