I've seen Range Rover Classic 60/40 seats fitted to a 130DC. Put the arm rest down and they virtually become 2 buckets.
A high back bucket seat might not have enough room to lean back on the ute body.
I bought a RRC Rear seat to see if it would fit in a 110, but it didn't. I fitted 3 Exmoor Trim bucket seats in the 2nd row of the 110, they're not as comfortable as the original bench seat, they obscure rear vision, and they don't fold down into the floor. The kids preffered the old seat.
I'd say you're best off leaving it alone and spending the money and time on a trip.
