So are you a filthy shipper, like I am?  I spent most of my free time today looking at Touhou fanart and cute doujins, so I'm a little saturated in shipping right now.

Probably my favorite find of the day, though I think I've seen it before.

Unfortunately, I don't think I know enough of the characters yet to ship them. ^^;;

I've seen a couple Marisa/Reimu ships, though. Are they a good pair?  

("Get out of the way, b****!")

Maybe.   As the main two playable characters and long time friends they have good shipping potential.   Marisa probably has the most ships of anyone, with the most popular pairing seeming to be Marisa/Alice.  This probably was spurred by the "Marisa stole the precious thing" video/song that blew up almost a decade ago:

In fan art/works, she's also one of the most likely to have multiple characters vying for her attention (usually tagged as "Everyone loves Marisa).  Most commonly, it's Reimu and the characters she's had as partners/assists in some games (Danbooru's images aren't sticking, so I just put the links):

The other two characters who get this "Everybody loves" treatment are Alice, ironically enough, and Rinnoskue (due to him being one of two? male characters on any importance). 

Reimu occasionally has gotten the treatment, though it's rarer; her shipping options a pretty varied as well.  Aside from Marisa, it's also popular to ship her with her fellow shrine maiden, Sanae, her bumming oni, Suika, and continual reporting annoyance, Aya.  Yukari, Remilia and  Youmu also thrown in often.  Of course, her first love will always be her donation box.

Honestly, Touhou is one of the franchises where I can ship almost anyone if the art/story is good, though I have my preferences.  That day, Marisa/Nitori caught my attention.

(Also, funny that you replaced a murderous sentient goat-Flower with an adorable, spherical grass-Bird).
