Arranging racks for different species?

[Lolo76]

Hmmmmm... I have two racks to house 3 different species, and need help arranging things! Basically I want to maximize space, while also ensuring that each species' husbandry is acceptable. Here's what I have in terms of the animals, and how each rack is laid out - any help would be much appreciated.

(species and approx weights):
2555g Ball Python
1800g BP
600-800g BPs x 5
500g BP
350g BP
600g Corn Snakes x 2
400g Corn Snake
30g Corn Snake
??g (tiny) Western Hognose
And I might be getting a pair of adult milksnakes in a trade soon...

Rack #1: 3x3' melamine, flexible sizing, belly-heat flexwatt wired separately (currently all plugged into one herpstat); each shelf can hold either one 41qt, three 12qt or 28qt/12qt Sterilite tubs.

Rack #2: 6-high with back heat, wired as one; each shelf holds a 32qt, I believe.

Picture of the melamine rack... I can unplug any of the flexwatt strips, or attach a second thermostat (to accommodate the colder-temp species).



And the 6-high rack, which currently houses 2 corns at the bottom...
