RF input to usb-uirt?

Can the usb-uirt be modified to directly pick up an RF remote signal?
I've got several Radio Shack 15-2117 8-in-1 remotes that I use currently. They send an RF signal to the base station where it's retransmitted as IR. Is there a way to have the usb-uirt directly detect the RF signal and avoid the RF-to-IR translation? I'd like to avoid any more IR 'noise' than is necessary.
I have a spare base station that I could cannibalze for parts.
