He proposed the health of the bride and the bridegroom, hoped that they would be happy together, and expressed a wish that all

their troubles would be little ones.

这是原句。

可以改成：

He proposed the health of the bride and the bridegroom, HOPING that they would be happy together, and expressed a wish that all

their troubles would be little ones.

可否将hoped改成hoping现在分词？ and后的expressed可否也同时改成expressing ?

如果可以的话，句子的含义理解有何变化？语法上是否允许这样更改？
