I think so? I have never done it, but thought that is what you guys wanted to do. @Ragan may know more how it works.
I got this from the website just now that we use for hosting:
ARK ABERRATION
We fully support Ark Aberration expansion pack. Ark Survival Evolved’s subterranean DLC for December.
CROSS TRAVEL
Full cross travel support. Link unlimited amount servers together, host more maps or mods and travel between them with your dinos and gear.
EDIT: Hmm, I was just checking out my client area and found some information on clustering game servers. I was going to see if I could set up an Aberration server, but I believe it said they were currently out of stock. Ugh. I guess I should have tried to order earlier in the day or yesterday. I will look into it.
