NO

You can try to change input states by capacitive coupling a glitch on the output to toggle states, using Miller capacitance, but that would be a transient. High Z inputs floating are prone to all kinds of stray crosstalk. so this is not useful.

You might see an effect with a NAND , NOR, INV. But not with AND, OR as these are double buffered. Of course this depends on crosstalk on the layout.

You can however, toggle the output state of a Flip Flop, by back driving a current glitch of opposite polarity. So FF’s make poor long cable drivers.

All digital logic devices are “analog”. To understand fault conditions you propose, you must examine the analog conditions like reverse gain which is very low.

Why not test your theory with controlled impedance and responses? With adjustable floating bias and very high Z buffered probes. It might be a waste of time, but then you may learn some things about crosstalk.
