Where are your 6 channels going?
I'm thinking about a few options as well:
SWS8 + amp
Amp OE under seats
Trunk sub + amp
Other option is replace front speaks and add sub with a 5 or 6 channel amp like you mentioned. Does everyone get the MS-8 by default? I have L7 and I'm unclear if that's a must have.
