都可以：
（by doing this/consequently）I/we shall not only + 动词,but also(+ 动词) = plain statement
（by doing this/consequently）not only shall I/we + 动词,but also (+ 动词) = 强调语气
比如：
Not only shall I miss the company of my dear friends,but (I shall) also (miss) the beautiful city itself.
I shall not only miss the company of...,but (I shall) also (miss) the beautiful city...
