    Horizontal movement of a guyed tower isn't part  of the typical equation. 
Free-standing towers are another thing. 
    You'd spend less time, effort and money to just  get a crane in there and 
mount the antenna on the tree itself. Apparently the  crane is a problem with 
your installation; e.g. no access, can't get close  enough, etc. 
    I don't have a big problem with your proposed  tree/tower installation. 
With proper brackets it should be just fine.
