It will take a more bare metal - real time approach. I've done a number of designs on both the OMAP and Sitara line from TI. It's a bit over kill for a bare metal and running Linux (remember all the test gear that had WiindowsCE or even more recent Linux based devices) isn't ideal. A purposed based embedded solution along with a update / modular combination of the Pica/Combo and maybe UHF/VHF (DSP-10) with a layout that would support a "remote head" would be ideal. The beaglebone is sold at or below the cost to manufacture and even in the Sitara line I've have seen a BOM less than $100. Its also a high pin count BGA where there is simply more to worry about going wrong.
Nothing up until this point has really put CODEC2 or other desired functionality in a openish platform for radio building / experimentation. The Combostar / Pica / DSP 10 is close but it dated. I use my combostar daily and have integrated FV into it but its kludgy and the AD DSP being basically set in stone limits what "could" be done. I recently did some prototypes of a VHF/CODEC2 HT and I can see that with some careful design it would be possible to have a nice platform for the home builder.
