Not sure if misunderstanding about relationship or motivated to improve herself as well

I'm having hard time to translate the first bubble, if someone can help, please.
I tried to transcript it:
"この特訓が赤城さんと加賀さんを結ばせる”何が”になるとは思えなけれど頑張るわ。。。"

Also, if I'm not wrong about the rest, that's quite a shocking declaration Zuikaku made here.
I can understand Shoukaku's reaction well.

Did not see that coming, I was expecting with not instead of

Thank you for your work firechikara

Ah, now Zuikaku has noticed the Shou/Kaga

I get "I can't imagine this special training becoming that "something" that binds Akagi-san and Kaga-san together, but I'll do my best..." Does that sound right in context?

Her expression seems more eager/determined than pained, so I'm leaning heavily towards "motivated to improve herself".

I'll use your translation because frankly I have no idea how to translate this one.
