Isn't already a thing (or almost)? For example Dell Latitude E7470 14" (16:9) [0] and Dell Precision 5550 15.6" (16:10) [1]:

Dell Precision 5550:

> Front Height: 7.70 mm (0.30 in.)

> Rear Height: 11.65 mm (0.45 in.)

> Width: 344.40 mm (13.56 in.)

> Depth: 230.30 mm (9.07 in.)

Dell Latitude E7470:

> Front Height: 17.2 mm (0.68 inch)

> Back Height: 19.4 mm (0.76 inch)

> Width 334.00 mm (13.14 inches)

> Depth: 232.0 mm (9.13 inches)

Precision is bulkier (cooling and dedicated GPU) and by about 10mm is larger (in width) but it is close to mimic 14".
