How to add/replace outlets with old 2-wire wiring?

My terminology is probably way off, but I'd like to know how bad of an idea this is:

I gutted my entrance last week. The wiring is copper 2-wire with no ground wire in metal flexible conduit. It comes off a sub-panel (with breakers) and then goes to several other rooms and outlets. I don't have access to all of the wiring so I can't simply replace all of it --- maybe half?. Also, all of the outlets on this sub-panel are 2-prong with no ground wire (unless the conduit if the ground?).

I'm wondering whether this is ok or not: replace the wiring that I can get at with 14/2 and connect to the existing old wiring. And instead of running the bare ground back to the sub panel, run it instead to the main service panel that's nearby.
