Why not? If you have an idea to build an interesting project related to GRC and want to use specific domain for that project, go ahead. I am sure whole team will support that.
It's all interconnected. Gridcoins.org uses @startail / @sc-steemit https://gridcoinstats.eu to check if we are in sync / not on fork. You can also use any resources of gridcoins.org for your own project. I would always support anything that GRC community will benefit from, and I'm sure others will do the same.
