It would be cool to have an inbetween size for the 1x3 platform and the huge 3x3.
The 3x3 is usually overkill, but the slim 1x3 and 1x3+1 T-shape ares often to small for complex 12 lane processors without it getting ugly.

maybe would be cool to be able to merge platforms to make them the shape you want?

Nah, merging platforms without limitation is a bad idea. It pretty much just removes the entire idea of platforms from the game. Getting stuff to fit in a smaller platform size is a huge part of the fun for many players.
What build are you playing that has 1x3 platforms? I want those. Maybe as a variant of the L-shaped?
