Would the NOINPUT > spending condition be hidden inside the taproot commitment? I'm not aware of a way to combine the setup and trigger transaction. The trigger transaction was introduced in order to delay the start of the timeouts until a later time, to avoid having an absolute lifetime limit and having really huge timeout. If we were to combine the trigger transaction with the setup transaction (which is broadcast during channel creation), all of those timeouts would start counting down immediately, and we could just skip the trigger transaction altogether. It'd be more interesting to combine update and trigger transactions in a sort of cut-through combination, but that doesn't seem possible outside of Mimblewimble.
