Sorry neither of those autos have a bellhousing to suit crossflow, years ago I did hear of a "factory" crossflow btr but I later found out that it was a bellhousing someone had made and tried to pass it off as a factory piece, as far as trans options for a crossflow using factory parts you are limited to what was available in 3 speed automatic xp, and xr to xf as they are all the same bellhousing pattern, so that's Borg warner 30/35 &40, c4, 3 speed manual (non synchronised 1st) synchronised 3 speed manual, 3 speed top loader, top loader, single rail, aisin 5 speeds that were in 3.3 xe's (made of glass) and t5's (good news is with the crossflow t5 bellhousing you can use any falcon 6 cylinder t5 from xf to el) anything else will need adapters or a custom bellhousing to work, ford changed the bellhousing pattern when they went ohc in ea so that rules out the later automatics, once you start talking adapters and modified torque converters the price of a c4 becomes far more affordable
I don't think there are c6 to 6 cylinder bellhousings, Ford did make a c4 to 6 cylinder bellhousing though, AFAIK c6 only came with big block and small block bellhousings with the small block variant being pretty rare compared to the big block version
