請英文專家，可以幫忙修正一句英文嗎？ 謝謝

If possible, I really hope (that) we can still be friends happily like we used to be. That will be great!

If possible, how wonderful it will be if we can happily be friends just like what we used to have before.

要看你對這件事有多肯定，有多少把握

很肯定
When there's a chance, I do hope we can be friends happily, just like before. How great that will be.

不肯定
If there's a chance, I do hope we could be friends happily, just like before. That would be great.

My answer:

If possible, I really hope we can be friends with happiness just like before. It will be great!

如果可能的話，我真的希望我們能快樂地做朋友，就像我們以前一樣，那該有多好啊！

If possible,I really hope we can be friends as happily as before. How wonderful will it be if things are like they used to be.
