Will a potential Sony 135 fe be "as much lighter" as the 85 fe?

Sonys 55 f/1.8 and 85 f/1.8 are small and light relative to comparable lenses, while having good optical and AF performance.

55 : 281g 64.4 x 70.5 mm

85 : 371g 78 × 82 mm

If/when Sony decide to make a 135 mm (non GM), is there any reason to believe that it can be small light and high quality compared to other 135mm lenses? I guess what I am asking is if the size benefits of the 55/85 are mainly results of the small mount flange distance offering new lens design possibilities, or if it rather a conscious design trade-off chosen by Sony for this line-up.

Canon 135mm f/2.0: 750g 83.0 x 112.0mm (+ converter)

Samyang 135mm f/2.0: 840g 82.0 x 148.0mm

Batis 135mm f/2.8: 614g 98 x 120 mm
