〜のがほしい instead of 〜たい


To start with, I'm not asking about how 〜たい and 〜ほしい (and their derivative
forms, like 〜てほしい, たがる, etc etc) structures work. I want to know whether is
natural/grammatically correct to say, for example, ラーメンを食べるのがほしいです instead of
ラーメン(を/が)食べたいです.




It's a grammatical sentence but its meaning is totally different from
ラーメンを／が食べたいです. It means you want _something_ that is related to eating of
ramen. It might be a doll that eats ramen or something like a bowl or a spoon
with which you eat ramen.

> ラーメンを食べる **の** がほしいです。  
>  I want **one** that eats ramen.  
>  I want **one** for eating ramen.  
>  etc.
