managing temps for multiple snake types

[IDvsEGO]

I am building a stack of enclosures and am looking into heat tape to simplify the heating and reduce costs. Here is what I am keeping and the temps that my internet searches have come up with

Mexican Black Kingsnake, Florida Kingsnake, Honduran Milk Snake - 84-88 degrees

Brazilian Rainbow Boa - 85-88 degrees

Red Tail Boa - 85-88 degrees

Ball Python - 88-92 degrees

apart from the ball, these all look like they could run at the same warm side temps. The red tail enclosure will be much bigger so I think she will get her own thermostat but for the 3 colubrids and the rainbow, is there a big problem with running the heat tape in series and all to a single thermostat? Would the ball be ok on those same temp ranges too or should I keep him warmer?

All of the enclosures will have the same heating element, dimensions and building materials. Each will also have its own hygrometer and a thermometer on both the warm and cool side.
