Yes, you will have widely more options for your array design by using exter=
nal microphones.
I notice the Shure MX391LP/0 is still available for cheap on eBay:

That one requires an adapter cable.
I don't know how much space is allowable between the boundary material and =
the microphone capsule - I would expect the highest frequencies would be fi=
rst effected by any gap.

That might be very hard to achieve with the odd shape.
