Using Airport Time Capsule as target/workplace for a Data Rescue III type software

I need to recover data from a 'bad' disk on a Macbook anno 2007. My idea is to mount the drive on a Macbook Air using target disk mode and a thunderbolt/Firewire connection. The mounting goes fine but copying the data leads to a hanging Mac Air. So now I put all hope on a Data Rescue type software in that such software will circumvent the hanging issue! Problem is that the Mac Air don't have enough memory to store the hopefully recovered data. Essentially, I have no proper 'target disk' for the recovered data and need to buy one (as well as buying the rescue/recovery software).

So, can I use a Airport Time Capsule as target/workplace for a Data Rescue type software on my Mac Air? Is this a proper mountable hard drive?

Thanks,
