Installing a salvaged double doorset in an internal opening

[lumor]

Hi. I'm planning to knock through a double door opening between living and dining rooms. I'd like to install glazed double doors in the new opening. I'm considering getting a salvaged late C19 double doorset with side and top lights instead of buying new. Does anyone know how feasible it would be to install this (for a professional - not trying to DIY it). The wall is a normal solid brick partition between front and rear rooms in a terraced house. It is w3900mm and h2820mm (finished floor level to finished ceiling). The doorset is w2050mm and h2660mm. It is a reclaimed patio/french door with all the jambs, timber frame, etc. (in one piece). I don't want to end up with bigger-than expected labour costs or give any joiners a nervous breakdown, but it seems like it should be doable. There should be 160mm above the opening for a lintel, which I'm hoping can go in the wall without having to open up the ceiling. There are no mouldings or anything. The floors are exposed floorboards in both rooms and all on the same level. Any insights would be appreciated. I'm trying to decide whether to buy the salvaged door. (It will fit through the front door and into the relevant room). Thank you!
