32bit vs 64bit and QuickTime/AVFoundation

I have a helper tool that needs to use both C-based QuickTime/QTKit as well
as AV Foundation to process things for the main app.

Currently I am actually using two helper tools - one 32bit app to work with
QuickTime (since some of the old API will not work in 64bit), and a second
32/64bit app to work with AV Foundation.

My main app calls on these helpers for various things.

I am considering merging them into one app, but it would have to be 32bit
only (though of course it will run on 64bit systems).

Is there any real drawback to this? I'd like to support 10.6 - 10.9 and I
know that if I merge them into one app, I'll have to link against 10.7 at
least to get AV Foundation. It would not be a deal breaker to drop 10.6
support.

Any other issue? Performance?

For communication with my main app, it would be easier to have a single app
thank I could ask to use either QT or AVFoundation rather than having to
talk to two different apps.

Thoughts?
