Does Such a thing exist?
looking into setting up a murs setup.
I'd like to go with moto mobiles, bases, and ht's.
I'm guessing as long as the radios are 2 watts they can be run on 154.570/600 frequencies (aka: MURS Ch 4/5).
Maybe a 2 watt mobile with base tray and power supply and a Stacked folded dipole array along with some LMR-400 will get me out good.
Looking to tinker with MURS a bit to see what kind of potential this service has.
I have a load of those 19-1210 2 watt mobiles from radio shack, but i'm kind of a die hard moto man.

Sure, 2-10 Watt LPI(Low Power Industrial) models of the maxtrac line are found quite often in V and UHF.

I'd love to lay hands on some 403-433MHz 2W LPI maxtracs... Especially ones with 16 pin connectors...

What about turning the Tx power down to the single-digits on a more powerful radio? Would that work?

The problem is that you'd be running the radio's PA out of design specifications and creating the potential for spurious emissions, etc. Turning a PA down lower than 50% of it's rated power is not advisable.

Umm...
The majority of the MURS channel require uber narrow deviation radios along the lines of 2.5 KHz...
Turning down the power of a narrowband compliant radio will likely cause all kinds of spurs outside of that narrow bandwidth...

Another choice you have would be a handheld connected to the outside antenna or plugged into a convertacom running on a power supply.
