Yes, but the number of transactions in 'bitcoin' as it's currently defined is severely limited (blocks are already full at a $15 per transaction cost). Conceptually, making something which increases the transaction count involves forking bitcoin, and a fork which aimed to do exactly that was denounced heavily by the community and rejected by the markets. The marginal cost may be small but the cost per transaction is high, by design, and by design which has extremely heavy resistance to even small and simple changes.
