That's happening, Balog.
Only problem is, it has to be combat-related, for now, and is categorized as Combat Related Special Compensation. That's what I have in the works for my own disability rating:

It started changing in 2004, but only for a small category of qualified disabled vets, with 50% or higher disability ratings:
http://www.military.com/benefits/military-pay/retired-pay/retired-concurrent-receipt-overviewI just sent off the paperwork to have part of my disability added to my pension, vs. being siphoned off into a separate VA payment as an offset. Luckily, I had the combat records to include in the package.
There was a law passed in the late 1800s that precluded disability income from being received concurrently with military pay, in an effort to reduce what was considered double-dipping by Civil War vets. Military retirement benefits were instituted in 1861, and within 30 years Congress banned the receipt of both a military retirement and disability compensation. Their justification was that a military pension was compensation enough for any disabilities incurred during the individual's term of service. That stayed in effect until 2004, see above.
