Would any alkene possibly aromatize with proper conditions?
Your thought is actually happening in real life. Petrolium industry uses the same concept except for polymerizing ethene (may be that also used to get higher alkanes). Fluid Catalytic Cracking (FCC) is one of the most important conversion processes used in petroleum refineries. FCC (see the schematic diagram below)) is widely used to convert the high-boiling, high-molecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline, olefinic gases, and other products such as aromatics (Ref.1):

For example, a conversion reactor is used to carry out several reactions. A few of them are:
$$\ce{n-C26H54 -&gt; C6H12 + C6H14 + C10H20 + C4H10}\tag1$$
$$\ce{C10H20 -&gt; C6H12 + i-C4H8}\tag2$$
$$\ce{C6H12 + 3 i-C4H8 -&gt; 3C4H10 + C6H6}\tag3$$
The equation $(1)$ (cracking reaction of paraffin) shows the formation of cyclohexane from a long-chain paraffin. The equation $(3)$ (hydrogen transfer reaction between cyclohexane and isobutene) shows the conversion of cyclohexane to benzene.
