IIRC the whole reason for acquiring TCF in the first place were scope restrictions w/ CHQ & the 170's so I don't think that's possible, I might be wrong.

But you're taking bout making them actual individual, separate entities. Technically I suppose you could but IMO that'd be so much work and effort w/ staff, manuals, certification, etc that it'd be more trouble than it's worth. Not to mention seniority integration (or in this case it'd be really the opposite of integration, whatever THAT word would be, lol) issues...it'd be a whole mess
