COULD??? we make a bigger tube and custom mount the AFM electronic unit on the pipe to allow more air to come in without triggering fuel cut?

is this possible or the electronic unit has to be specified according to the size of the AFM body???

its just an idea I had thought up.

It's been done before. The problem is if you go too big then the car won't run properly. If you don't know exactly how much bigger then stock or Lexus AFM your custom pipe is then your car will have it's A/F ratios way off and may not run at all. There's a lot of tuning that you'd have to do, proper injector sizing, etc. I prefer to just spend the $100 on a Lexus AFM since it's sized pretty well for 550cc injectors.
