MacOS X Time Machine question

Is there a way to restore files from the MacOS X Time Machine backups to an entirely new disk (different from the original disk, and not an identical replacement of the original disk)?

In my case, the MacOS X 10.7.5 update broke NEC Spectraview, and I'm unable to calibrate my monitor.  I don't want to do what some have done, which is use Time Machine to downgrade the current installation to 10.7.4.  I simply don't know what it might overwrite.

I have a Mac Pro in which I had a spare disk slot in which I put one of the disks I had lying around; I want to restore 10.7.4 from Time Machine to that disk. 

Right now I don't see any way to make Time Machine do that (and if it is not possible, Time Machine should not be considered to be a back-up solution!)

The other solutions I've tried:

1. Try download from the App Store where my MacOS X Lion order was still visible - that gives only 10.7.5; not 10.7.

2. Write to Apple Store support.   That was worse than useless.

I'm not an expert but you could try accessing your data from a linux machine. See, e.g., http://superuser.com/questions/238297/accessing-t...

This is an interesting dilemma. TM will not work and Apple advises as much here: http://support.apple.com/kb/HT4491 where they warn against trying to restore an older version of the OS. There is some method in their madness but I'm not about to defend it.

Some ideas:

1 - Find a friend running 10.7.4 or earlier, uses CCC to copy it to a new drive, boot from that drive (hold Option key at restart to see the drive choices). Use TM to restore your data, apps and user files
2 - Wait for Apple's/NEC's promised fix in ML 10.8.3/4 then upgrade to ML
3 - Go back to Snow Leopard as you can buy intsall disks on eBay. Intsall to new drive, use TM to restore data, apps and user files. Let's face it, Lion did not add much and broke Rosetta in the migration to 64 bit.
4 - Buy a (used) EyeOne Display 2 ($40-80 on eBay) which works fine with Lion and Mountain Lion - I speak from experience. I think (not sure) that this colorimeter is the same as used by NEC but uses xRite's app. D/L latest software (which happens to still be the Lion version) from xRite free.
5 - Do not buy a Lion installer USB thumb drive. When I had my 2010 MBA which came with one it was locked out and could only be used on laptops, not on desktops.
6 - Consider a torrent download of the 10.7.4 or earlier installer. Yes someone stole it, but as you already paid for Lion I see no crime here.
7 - If you are desperate for a quick fix, email me with a safe shipping address and I will mail you my EyeOne Display 2 which you can then use to update your profile. I use it once a quarter so will not miss it, having just done an update in my three Dells.

Thanks Thomas, especially for the kind offer to lend me your EyeOne. I think I should have Snow Leopard install disks lying around somewhere, that may be the best thing to aim for. It will also encourage me to tidy up and organize :)
