Do it!! The TE combos, though great to use, are far too cumbersome to be practical to those of us of a certain age with "well used" backs who need to move their gear.
Personally, I'd pull the head and rack it. They are manageable this way (12kg - ish?).
Leave the combo intact but transplant the speakers into another cab (I have an empty 2x12 cab with grills if you need it) - just replace the "face" for one with two 10" holes.
Doing this means you can finish the cases any way you like - I was well impressed with the blue snakeskin head and cab that were for sale here recently.
You can also transplant all the parts back into the original case if Bruce Banner ever comes round with the cash and wants to buy it from you.
