DL3 lens options?

I have someone bringing in two DL3 units to my place on Monday.

The throw from my DS truss to my US wall is 20', and the girl bringing the units in told me that she needs 28'. Putting the DL3 28' from the US wall is not an option, so she needs different lenses... (she has run into this problem at most of the venues they're playing in)

What are the lens options for the DL3? Obviously, she's not carrying the right ones...
