Ive ran into the issue of my Aroma top not fitting with my Miyuki Pimp Cap which brought me to the question as of if a custom aroma top is something that customers could get made

Yes, with a pimp cap it makes it very hard to have an aroma top work.  Pimp caps can get tall and bulky.  We suggest removing the cap to allow the aroma top to work.

BE CAREFUL, the pimp cap will get HOT

YES, you can have a custom aroma top made also.
