Welcome to CPF 
As long as the batteries in the adapter are in parallel it makes very good sense, it allows you to use AA rechargeable batteries which are cheaper and more commonly available than D size rechargeable batteries. Brightness should remain the same.

It would not, however if you were to use series adapters such as #16 in http://www.cpfmarketplace.com/mp/showpost.php?p=1423749&postcount=1 and then used a MagNum Star 5 cell bulb (if using NiMH batteries) or a MagNum Star 6 cell bulb (using alkaline batteries), you'd have a pretty bright light in a relatively compact package. Using the AA adapters also makes the light a bit lighter than with 2 D cells.

Multiple parallel AA to D adapters also allow the use of lithium AA batteries in a D cell light. This may or may not be advantageous, depending on your individual circumstances.

I have a 128 LED light that uses 6AAs in 2x3AA (serial/series?) adapters. Pulling these out, I was unable to put a D cell battery back in their place. The barrel was just a hair too tight. Not all lights may be like this, however.
I do have a Garrity stainless 4AA incan (with camo cladding) that uses a single 4AA adapter ... and a single D cells fits quite well in its place. I'm 99% sure this is a series adapter (making the light a 6 volt) as the lone D cell (1.5 volt by itself) barely makes the filament in the bulb (KPR113) glow.
The KEY to swapping these around is knowing whether the cluster adapter/carrier you have or are intending to buy links the cells serially (adding the voltage together) or in parallel (just adds more capacity while leaving the voltage the same as printed on the side of any single cell).
If you buy 2 - 4AA (series/serial) carriers, load them full of batts and put them into a 2D light you would be going from a 3 volt set-up to a 12 volt set-up. The bulb will likely 'instaflash'
the first time the light is turned on and that will be the end of the bulb.
You might be able to find 12V bulbs (does the light use a PR based bulb?) and you'd have a wicked bright light ... but run-time will be poor. This might not be a terrible thing if you don't need it for long periods of time AND you are using rechargeables. :shrug:
