     Well, this is an engineering question and has to do with the overturning 
moment of the tower which is determined by professional engineers at Rohn. If 
in doubt, follow the LXC Prime Directive - "DO what the manufacturer says".

    OTOH I suspect that your proposed change may not be fatal to your 
installation since you have the same amount of concrete in the hole and the 
same amount of contact area with the earth. (Note - I'm not an engineer and 
don't play one on television.) Check with an engineer before you make the 
proposed change.

     What are you installing on this "TV tower"?
