is it possible to design a multi sim card reader??

hello everyone...
I am punit.. i am not an expert or very knowledgeble person in the field of controller and processors... i am just a creative student... and hope u people can convert my creativity into the reality...

actually the idea is.. we have 2 design a multi sim card reader (like a multi card reader) which can be accessed from a PC, we have to access all the SIM features on our PC, dat means we must be able to get connected with the corresponding network on our PC itself...
the idea came into my mind when i looked a mobile recharge shop, for 8 GSM companies the shopkeeper was having 8 moblle phones, if one fails he has to change the SIM card to another cell phone... if he will have a system like this.. he can be very comfortable with this, he just have to open a window, select the specific SIM among those 8 inserted in the SIM reader...
i dnt knw, wat i m posting here... m sry if its not good...

Hi Punit

Your Idea is good enough but when we implement it in hardware we will find actual problems like Switching,( when u switching from one sim to another the modem has to be reseted).

I think some thing like this

you can make use of analog switch ICs take a look at seirra wireless application note for dual sim with switching.
