I would think a 100k input load would give you too much insertion loss to be practical. However I think this would work for your MMG's.
R-HP = 6190 ohm
C-HP = 1.7 nf
R-LP = 5600 ohm
C-LP = 120 nf (0.12 mfd)
I calculate the insertion loss to be -2db and the minimum input impedance seen by your tube stage is 4740 ohm.
