Phone Bluetooth Hub

Hi guys.
I need to know if i can create a mobile gateway using BT Modules.
My idea is to create a "Black Box" with 3 or more BT modules for connect in the same time my Car BT systems to two or more mobile phones at the same time.
Someone has some ideas?

You may run into desensitizing issues having 3 antennas on the same band operating in such close proximity.
It's been 30 years since I sat for a radio license exam and I've probably forgotten a good bit, but I think that's correct.

BT is spread-spectrum though, which is much more rubust against co-channel interference.

Pretty amazing tech then. Have you had success using multiple Bluetooth modules in the same box before?
