So there are no technical limitations prohibiting the intentions of the original poster. One man's "unnatural" is another man's knowing when or when not to violate a rule of thumb. The latter being a non-technical consideration. If the networking people are worth their salt, IMO, they would code both the old subnet and the new subnet on the switch port anyway to allow a graceful migration of the guests from the old subnet to the new subnet so that a "flash cut" of the network and all guests are not required at one time. That would certainly allow the new guests to be immediately implemented while the old ones migrate on their own schedule to the new subnet. Then the only question would really be, does the old subnet go away or stay, a potentially separate question.

In a purely switch based networking configuration, mutliple subnets may be defined on a single broadcast domain even if it is accessed by a single access port (non-VLAN). The default gateway would need to be configured with addresses for both subnets and for devices on the same broadcast domain with different subnet addresses to communicate they would need to go through the default gateway. Admittedly, this violates the rule of thumb of one subnet per broadcast domain but is supported by the technology.
What is the source of this restriction?
There isn't really a restriction, but it requires an ... unnatural ... configuration, liable to cause more problems than it solves. The problem areas will be getting it past the network security folks and routing.
