How to say each other on this sentence

Question

could you help me with this? I'm trying to say "If we call each other, will we be able to understand each other at all?"

so far I have come with this [僕らはお互いを電話すれば、お互いをわかりますかな?] What you guys think?

I'm not really sure if that's the proper way to say it, and also not sure about how to say "at all".

ありがとうございます！

Answer 1

僕らはお互いを電話すれば、お互いをわかりますかな?

• 僕らは is not necessary because it's safely inferred from the context.
• Unlike call, 電話する is not transitive. The particle you need here is に. Or you can just use お互い without any particle because it also works as an adverb.
• ～ますかな is a very pompous way of asking a question. I hear this only in fiction, typically from noble people and stereotyped elderly gentlemen.
• Neutrally saying ～ますか is not a good way to ask a question like this anyway, because you are expecting a positive response. (i.e., You want to say "we do ... don't we?" or "Don't we ...", not simply "Do we ...")
• 分かる is rarely used transitively. Use ～が分かる isntead.
• Try using ～あう here. If you can use this the second お互い is redundant.
• "At all" in a positive sentence can be translated as とにかく, ともかく, 何にせよ, etc.

Fixed version:

• 僕らはお互いに電話すれば、お互いが分かるのではないでしょうか。 (still a bit clumsy)
• お互いに電話すれば、とにかく分かり合えるのではないでしょうか。
• 何にせよ、お互い電話すれば、わかり合えるのでは？
• 電話で話しあえば、ともかくわかりあえるんじゃない？ (casual)

Answer 2

I would put the line you quoted - If we call each other, will we be able to understand each other at all?" in Japanese as;

「お互いに（電話で）話し合ってみれば、兎に角解り合えるのではないでしょうか？」

As you know, in Japanese, particularly in spoken form,the subject (I, we,) is often dropped.

In addition, 「お互いを」電話すれば sounds awkward, and its repetion - 「お互い」を電話すれば「お互い」を分かる is felt redundant.
