I was asking if something is possible or not, and received the "ありじゃないかなぁ"
answer below.

I had never heard this expression, is my translation correct?

My translation of the answer: We have to ask to be sure, but I guess it is not
possible.

Meaning of ありじゃないかなぁ
To explicit Chocolate's answer and by the way answer gibbon.

ありじゃないか should be read as "[something]じゃないか" that you would basically
translate as "Doesn't/Isn't it [something] ?". Even as a negative form, turned
as a question with the ？/か/かな, it becomes a _positive wonder_. Like a question
tag. Plus, you should not see it as a question directed to you, more like the
person speaking to him/herself and just expressing his/her wonder out loud.

The [something] itself, can be positive or negative, it does not matter. It
will mean "Doesn't/Isn't it [something] ?"

To Gibbon> でしょう／だろう can be used for similar cases. Ex: you don't find
something, it would be 100% normal to say "どこでしょう？" speaking to yourself or
someone else.

answer
あり is a slang meaning "be acceptable", "can be dealt with", or "be cool", (or,
more literally, "exists within the acceptable domain"). See [my answer to this
question](https://japanese.stackexchange.com/questions/4642).

As for the question part, you translated the opposite. Here, you have a
negation, but that is used rethorically. Just like the English negative tag
question `isn't it?` implies affirmative, so does the negative question here.

The whole sentence means

> I am not sure without asking to someone, but isn't it acceptable?  
>  I am not sure without asking to someone, but I suppose it is acceptable.
