Kagami and Tsukasa? Maybe?

I would say so

First thing i thought

That's what I thought too, but the lack of lucky star related tags in pixiv stopped me from tagging the picture as such.

After all these years, a new Alice and Maria pic! I used to spend alot of time hunting for new art works for these two back in the day.

Pic is now at http://www.pixiv.net/member_illust.php?mode=medium&illust_id=9854387

Pixiv source confirms it is from Suigetsu, so no.
