Questions about a bowl

[Knifeeyz]

So,i recently got a new hookah bow,it's a 10 euro bowl but for now i have to use this until i can get a new one.

So the question is,the bowl is like a ferris bowl,it has a big lip to hold a HMD but i don't have a HMD so i was wondering if i could use foil,and if t here would be much difference in smoke output since there will be a big if you could say gap, from the tobacco to the foil.

Will this work fine with foil?i mainly pack it very loose and upto the first lip,where the hmd is supposed to stay.

Here's the bowl https://imgur.com/gallery/rX9tT7O
