Schoeps MK4 > KCY 250 > Sonosax SX-M2/LS2

It might run you a little over $2000 (maybe $2400) but it is the best choice for stealthing. It is where I see myself a few years down the road. It would also be a wonderful FOB set-up.
Otherwise, your best bet is DPA 4060s > DPA mma6000. That would most likely run you $1100. Nice but I don't imagine it is what you are looking for in a FOB set-up.
fwiw I usually don't share prices but this is what the costs were for me.
MK4 Matched pair: $900 Used (I have seen some go for $800 recently)
KCY 250: $525 Used
Sonosax SX-M2/LS2: $945 New
Very worth the money IMO...
alternatively:
NBOX $1200 New
MK4 Pair $800-900 used
Another option would be trying to get some AKG CK1x,2x,or 3x capsules, AKG CK91,92,93 (for the 300 blueline series), or KM100 capsules and running them into the lemo in on the sonosax, they would all work.
