Did you mean that the guy anchors will be located at different elevations?
If so, this is not a problem. Both of my Rohn 45 towers (100’ and 130’) are located on elevated ledge and have two guys on that elevation. The third guy wire of the 130’ tower is located about 10’ lower vertically and about 80’ further away from the tower than the other two (95’, 90’ and 175’ away). The third guy wire on the 100’ tower is about the same distance away from the tower as the other two but is also about 10’ lower and of similar length.
This has never been a problem through multiple tornados, hurricanes, and countless violent T-storms, icestorms and blizzards.
The bases of both towers are deeper and wider with more concrete than is required and the guy anchors are are similarly installed. I use 1/4” EHS with preforms and ice clips.
I don’t know that this would have been required for to safeguard the 10’ elevation difference and greater lengths, but I thought it to be prudent “insurance”.
Follow the Rohn specs – however, it is certainly ok to make the installation “beefier” than required.

I am installing both a 55G and a 45G. In both cases, ONE of the radials is
15 feet lower than the other two.
