AssFace's Journal: Been a long time since I rock and rolled

It has also been a long time since I posted in this journal.

I have this idea that I want to get geek feedback on. I will post it here in this journal in the hopes that smart folks will read it and laugh at me. I am contemplating submitting a version of it to Ask Slashdot to get even more feedback.

The idea:

I have a bid out on EBay for one of the old school brick cell phones, it looks very nearly identical to this one.
With that phone, I'd like to also buy the largest, cheapest GSM phone that I can find and gut the two phones. I then want to put the working parts of the newer GSM phone into the gutted shell of the big old brick.

The end result is a functioning phone without the health hazards but with all of the coolness of obscenely large phones. I could wall down the street yelling "BUY SELL STOCKS BONDS" and "THE MARKET NEVER CLOSES!"
Doing that with a tiny phone or worse yet a Jabra device and people think you are just insane instead of... well, insane but on the phone and at least talking to someone else... theoretically.

Whatever, the point being I want to swap the guts out and carry around a big obnoxious phone just to fly in the face of conformity.

I am hoping for any suggestions and or ideas on what pitfalls I may run into, or things that might make it easier.
I am not interested in a working old device - that stuff can hurt you. I just want the shell.
Is someone else already selling something like this? If so, I have no interest in doing it - I don't plan on selling them, but I don't want to work on it just to find out I could have just bought one.
