dot blot without phenol/chlorof extraction and precipitation?

i'm going to do a DNase digestion of my RNA samples after which i 
would like to load them directly on a nylon membrane (hybond N+) 
using a dot blot apparatus. I would like to ommit phenol/chloroform 
extraction and ethanol precipitation, because I have many samples and 
for reasons of subsequent quantification I don't want to introduce 
any further potential differences.

If someone has done something similar or could tell why i shouldn't 
do it, i would appreciate it very much.

Thanks a lot in advance,
