In the Australian and New Zealand markets, Uniden has a couple of radios that combine a UHF CB (their version of the GMRS in the USA) with a UHF scanner radio. Here's a link to one:

What I'd like to see, would be a GMRS mobile transceiver with a 380-512 MHz (only) scanning receiver side-by-side in the same case, like a Ham 2m/70cm dual-band radio.
The GMRS side would cover the 7 interstitial channels with a menu-selectable power output of 1-5 watts so as to help the licensed GMRS user to select the appropriate power output depending on the gain of their antenna in order to stay within the 5 watt ERP limit of those channels; receive only of the FRS channels 8-14; and GMRS channels 15-22, with selectable power outputs of 5 watts minimum, and 40-50 watts maximum. It would have full CTCSS/DCS, as well as DTMF signaling. It would be narrow/wide selectable. One button press repeater-simplex selectable on the main GMRS channels.
The scanner side would have all of the latest digital modes and trunktracking capabilities of the current high-end scanners, but would limit its coverage to no more than 380-512 MHz, so that the circuitry and firmware could be optimized for the UHF band, instead of making compromises that are needed to cover the multitude of bands that regular scanners cover. (Keeping the scanner coverage in the same range as the transceiver, would also allow for better reception compared to using a CB antenna to try to receive VHF/UHF/700/800 as the BearTracker 885 CB/scanner combo appears to try to do. Unless it has a separate antenna connector for that? And a full fledged scanner would have better reception at a distance than just a "Close Call" type receiver, which at first glance is what the BearTracker 885 appears to have.)
A MURS version that combines a full-fledged MURS mobile transceiver alongside a 108-174 MHz scanner would also be desirable to me.
I would use the scanner section to monitor all of the interoperable channels in their respective bands (VTAC's, UTAC's, local channels such as V-AIRS and U-AIRS, etc), emergency management (local as well as the Federal-State Incident Response, FEMA, Disaster Medical Response, etc) along with other selected channels that aren't used very often, or which I wouldn't want taking up memory space, or the time to scan them, in my regular scanners, such as the railroad channels, and perhaps the VHF Marine band.
I don't know how much of a demand these dual transceiver/scanners would have, but they're something I've been interested in seeing since I first ran across one of Uniden's UHF CB/scanner models, the UH-015SX I believe it was.
