Greetings Strickman451,
While you can use the supplied overhang gauge, the first thing I'd do would be to thoroughly read the Feickert and MintLP alignment threads currently running on this forum.
I would then carefully visit my setup with your current Dynavector. I cannot emphasize this strongly enough. Palasr and I convinced Doug Deacon to acquire an arc style protractor from MintLP and it resulted in nothing short of an epiphany for him. Get the best out of your current Dynavector before going to the same effort with an XV-1s.
Once you've truly optimized your geometry, you can start thinking of an XV-1s. You will note that the distance from the cartridge mounting holes to the location of the stylus varies on the Dynavector models, so at a minimum, you will be revisiting the geometry on your second headshell. As noted, the XV-1s is heavier. It is also taller - at 21mm from mounting plane to stylus, so your height (VTA) will change. I've laid out some of these dimensions in the 8th post on this thread:

Cheers,
