Yes, i would do that. Nice to have a new station on the bnd soon. I 
already noticed your dx cluster entries during my CW activity ;-)
I expect tha the 10m toploaded vertical will work well. But do not only 
use radials: It is important to use ground rods on LF/MF. A 2m deep 
metallic rod should work better then all radials together. Just start 
experimenting and see the different results. It is fun anyway :-)

A good idea too.
