14.4 to 18.8 adapter?

Does one exist? I have a. Well I think it could just be a san francisco thing, The Skull Original perculator thats an 18.8 joint. I use a 18.8 to 14.4 adaptor for an ashcatcher that I found for very cheap. I know i could spend a lot of money on an 18.8 roor 3 piecer that would be awesome, but this works fine and I enjoy it except for the fact I have small 14.4 bowls and I don't need to buy anymore. Is there a 14.4 to 18.8 adapter available? I haven't been able to find one.. and my fat 18.8 bowl is getting lonely :jointsmile:
