Pauli’s exclusion principle So here’s what the exclusion principle states:
“No 2 fermions( let’s say electrons) can have the same quantum states”
Consider the following hypothetical situation:
Let’s have 2 free electrons in a vacuum. They are also free from gravity. Is it possible to modify the exclusion principle in to the following statement:
“ No 2 fermions (electrons) can occupy the the same position in space and time simultaneously”

I state the above because the electrons are not bound to any atoms. The 2 electrons also have different spins. 
 A: You need also to account for spin.
One way to answer your question is rephrase it as the statement that the total wavefunction of a 2-fermion system must be fully antisymmetric.  If the spin part of this system is antisymmetric, i.e.
$$
\vert\chi\rangle = \frac{1}{\sqrt{2}}\left( \vert +\rangle \vert -\rangle -
\vert -\rangle \vert +\rangle\right) \tag{1}
$$
then the spatial part can be symmetric and then two fermions could occupy the same position (if they didn't interact) in the sense that the probability density for $\vec r_1=\vec r_2$ would not be $0$.  The probability of finding them both at exactly the same point in space is $0$ since the integral of this distribution over an area of size $0$ (i.e. the line $\vec r_1=\vec r_2$) will be $0$.
Of course the electrons would interact through electromagnetic repulsion, which would push them one away from the other.
A: This is exactly what happens in the orbitals of an atom or molecule. The orbital describes the probability (amplitude) distribution of the electron, so when two electrons occupy the same one, they do have the same position state at the same time. There is nothing fundamental that prevents them from being found in the same region of space at the same time, so your modified statement is false. Pauli exclusion doesn't forbid this because the full state of an electron also includes its spin. Since electrons have only two orthogonal spin states, no more than two electrons can occupy an orbital (i.e., exist simultaneously in the same position state).
Another point that may be of interest to you: when two electrons occupy the same orbital, Pauli exclusion does require that they have opposite spin. Spin is a vector that can be measured along any direction, and Pauli exclusion must be satisfied regardless of which direction is chosen by the observer. The unique spin state of two electrons that meets this condition is an entangled state called the singlet:  $\frac{1}{\sqrt{2}}(\lvert\uparrow,\downarrow\rangle-\lvert\downarrow,\uparrow\rangle)$.
A: The question is really hypothetical because any two electrons will repulse each other due to their identical charges. But let’s consider they will not feel the Coulomb force.
Your stated principle

No 2 fermions (electrons) can occupy the the same position in space and time simultaneously.

does not make sense. Where one electron is a second can’t be. But let’s consider that the two electrons are near to each other (not feeling the Coulomb force). Furthermore Pauli’s exclusive principle states


The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously. (Wikipedia, bolt letters by me).


Electrons have two fields, an electric field and a magnetic dipole moment. In the quantum system of an atom the electric field is neutralised by the nucleus and the magnetic dipole moments are prevailing. That any two of the electron’s arranging each over as a pair of interacting magnets is not a surprise (in our modern days). Abstracting that your electrons do not feel Coulomb force, they also will align each other with north to south poles.

I state the above because the electrons are not bound to any atoms. The 2 electrons also have different spins.

Two electrons without any interaction do not have spins in any relation to each other. The spins will be oriented in random  direction(s) in space. During the approach of your electric neutral electrons of course the dipole magnetic moments orient each other and the spins are anti-aligned at the end.
