MK99,

What you can do is merge them with caution...Look thru' every folder and .css file individually an see what are the differences...Also you can do a diff on a .css from f2thak and from blanco to see the main differences...

Could you tell me what tweaks you want from N9QTweak that are only applying to blanco and not to F2thak's theme?

Maybe I can help you with alternative solutions instead of doing a merge...
