いいといい ? Valid?

Just a question regarding the といい (N4) grammar construction.

Would a sentence like 食べ物はいいといい sound natural? Based on the description, I don’t see why it would be grammatically incorrect, but is it normal to follow the i-adjective いい with といい?
A quick search yielded no examples that I could find.

I think it is valid. There is native content with this sentence:

天気がいいといいね。

I Think I have seen this with the よいといい version as well.
