No. Benzene is an aromatic ring. It has C-C=C sequences that easily flip to C=C-C, making electrons in the ring highly mobile. A C≡C-C sequence does not easily flip to C=C=C, or vice versa. Those electrons are a lot less mobile. Also, alternating single and double bonds leave a bonding site on each carbon for a functional group. Alternating single and triple bonds use up all four (easy) carbon bonds, and you can't cram another bond in there without an insanely powerful acid.
