I've already used "thinking of it." Example:

Thinking of it, maybe I shouldn't knock on that door.

I made a Google Books search.

There are similar phrases but I couldn't find a sentence that starts with "Thinking of it,"

So maybe it's not a common phrase? Still, can I be used to replace come to think of it? Or there's a better option?

Thinking of it and come to think of it are phrases that people use in different circumstances.

Taking come to think of it first, I like Merriam Webster's explanation: —used in speech to say that one has just remembered or thought of something

Collins English Dictionary offers indicates that you have suddenly realized something, often something obvious

It's an idiomatic expression that one hears in conversation all the time, signifying that something has just occurred to the speaker.

Thinking of it (or, more often, thinking about it) is likely to be used in a completely different context, generally at the head of a sentence to talk about something that you have reflected on; or possibly to contrast thinking with doing:

Thinking of it is one thing, actually doing it is quite another.

Thinking of it has made me realise just how lucky we were.

By the way, one knocks at or knocks on a door. One does NOT knock a door.

"Come to think of it" means that you are adding some additional factor to a decision. The standard alternative way of saying this would be "Thinking about it again" (or some variation like "thinking about it some more"). If you decide to take a complete opposite decision, you can also use the standard phrase "on second thought".
