That depends a LOT on which canned converter you decide to buy,
if you only go after price, or W/mm³ capacity, then certainly yes.
But for a one-off application like this, any money saved on a
cheap model is easily lost many times over in the trouble it will
cause.
But returning to the original post: Has anybody ever characterized
how much difference it makes to use two different PSU's for heater
vs. electronics sides of telecom Rb's ?
I'm sure there is a reason why they make it two different pins ?

Never attribute to malice what can adequately be explained by incompetence.
