Dilemma HO layout plan

[Canadian Atlantic Railway]

I have come up with a new plan (In my head). I am thinking a two larger industries (Flats maybe) on back wall of the 12'.5'' section. Maybe plastic pellet silos and with manufacturer and a warehouse with a two spot dock and some storage tracks on the front half. On the 8' foot section two or three tracks for trans-loading of pipe, scrap, cement etc.

Thoughts or suggestions would be welcome.
