Here's a list of Warframes that should fit their characteristics/abilities with some of the characters in Touhou (not including the ones who have appeared in fan arts on Danbooru like the one above).
1. Zephyr with Shameimaru Aya
2. Vauban with all kappa in Gensokyo or with Kawashiro Nitori [They're engineers]
3. Nyx with Komeiji Satori [Since Nyx is a psychic-based Warframe, she could/can also do mind reading like Satori]
4. Saryn with Medicine Melancholy [Both of them can manipulate poison]
5. Oberon with all fairies in Gensokyo or with Daiyousei [He is named after the king of the fairies in medieval Europe and Renaissance literature of the same name (also spelled Auberon)]
6. Excalibur with Konpaku Youmu [Since he's a sword-themed Warframe and Youmu is mainly handling sword techniques]
7. Hydroid with Wakasagihime [Because he's a water-themed Warframe and Wakasagihime is a mermaid who lives mostly in the water of the Misty Lake]
8. Banshee with Luna Child and/or Star Sapphire [Banshee can manipulate sound (Luna) and use the Sonar ability (Star)]
9. Trinity with Yagokoro Eirin [Both are healers]
10. Nova with Reiuji Utsuho [Both having a stellar/nuclear theme]
11. Volt with Nagae Iku [Iku can borrow a bit of the Dragon God's power, which allows her to cause and manipulate lightning (electricity) on her own; while Volt's power can't match the strength of pure lightning, he can compensate that with the variety of his electrical abilities]
12. Mirage with Sunny Milk [Both having mainly an illusionary theme via light manipulation; Sunny refracts light to make herself invisible, while Mirage manipulates light for offensive, self-enhancement and environmental manipulation]
13. Valkyr with Chen [Since Valkyr has claws and an alternate helmet of feline appearance - like a cat - I think she can be paired with Chen. Although surprisingly, I'm somehow still thinking that this is debatable...]
14. Ember with Fujiwara no Mokou [Both can manipulate fire]
15. Limbo with Kirisame Marisa [His physical appearance resembles of a stage magician and emulates the image of a gentlemen thief. Not surprising since Marisa is a (ordinary) magician and often portrayed as a famous thief in fanworks. Oh, they both wear hats]
Who knows? After Marisa stole Patchouli's books from the SDM's library, Limbo might steal the books back from Marisa by using one of his Rift weaving abilities, i.e. Rift Walk, and return them to the owner, much to the frustration of the ordinary human magician.
Hilariously, I actually do color my warframes as 2hus. Some of them are pretty hard to pin down. I wont list them all but here are a few:
My nyx is Koishi rather than Satori since control and manipulation is more Koi's thing.
My Mirage is Reisen as opposed to Sunny. Becuase I can't quite get Flandre's color scheme to work...
Limbo is Yukari because dimensional phasing and leaving gaps behind.
Oberon is Minariko mostly because of the nature themes and because she's frequently a healer in touhou fangames.
Banshee was kyoko but I recolored her to be Toyosatomimi no Miko due to Miko's ability kinda fitting, that one banshee skin that looks like its wearing headphones, and because banshee looks REALLY good in purple.
I need to re-color hydroid to Wakasagihime since Murasa's color scheme does not look good on him at all.
Wukong makes for a good Suika
Titania is Yuyuko
Khora is Ran and Chen
Chroma is an obvious Meiling
Ash is Sakuya
Umbra is Toyohime
and Mesa is Reimu because who else has such a bullshit homing attack?
The only one I don't have a touhou color scheme for is Mag.
