Just
rent a rotary hammer and coring bit and drill new holes  for your new anchor
bolts. Use industrial epoxy to glue them in and you're  good to go.

down, like a US TOWER HDX series.  The vector forces  would be quite
different from a strictly vertical that doesn't lay down. Am I  correct?
 
    No. Not being an engineer I can't comment  authoritatively. But I 
suspect the forces on a tower that's being lowered from  vertical to horizontal 
is significantly less than the same tower  vertical in a big wind. The anchor 
rod epoxy is stronger than the concrete  so I don't see any reason why you 
couldn't do it. 
 
    I've used the above technique many times and I  think that all of the 
towers of interest for this were crank-ups.
