It also doesn't account for time dilation in a gravity well however i still think the general idea has some merit if you think of it as being bombarded by massless ‘action potentials’ on all sides with mass absorbing that field to some to enable translation in space time.
I get this is vague spitballing but essentially an ‘action potential’ would allow mass to move. Higher temperature mass interacts more, lower temperature interacts less. Mass with momentum would be biased to absorb more from one side so it travels in a specific direction in space more than others (the idea i’m getting at is that all movement in space only occurs with interaction with this field), this also would counteract issues with moving mass interacting more on a specific side - the very bias of mass with momentum to absorb more on one side means that from that masses point of view it has the same action potentials interacting from all sides. Mass shielded behind mass receives fewer action potentials so experiences exactly the effect that you can call time dilation. Mass shielding other mass from action potentials also means that mass accelerates towards other mass.
Essentially its the above but instead of a massive particle hitting other mass from all sides it’s a field that allows mass to experience a unit of time.
