OH *YES*!!!  We do it all the time...  Run the northern, blot it overnight 
(NaPO4 transfer), cross-link it, air dry it, put into a hybridization bag 
and wait until the probe is ready!  Once cross-linked, I've probed one 
Northern blot up to three times.  Sometimes we've waited up to a month 
prior to probing.

BTW - this isn't a stupid question!

Hope this helps,
