No? A hybrid powertrain is really expensive by itself, requires a more expensive-per-kWh battery pack, and has little efficiency advantage over an optimally geared Diesel engine in cruise, as it’s already running optimally.
And you’re only making a marginal improvement in CO2 emissions. All the synth fuels are much more expensive than electricity.

There are hills up and down, there's passing, there are bridges, headwinds and tailwinds, etc. Required power is different if you're fully loaded vs partially vs empty vs no trailer. Even on interstates there are towns every 50-100mi that have their own traffic and thus non-cruise speeds. If the exception to cruise is only 0.1% then I agree it's dumb to consider. If it's 10% or more and the emissions during non cruise are significantly worse, it could end up accounting for 30-40% of total emissions instead of just 10%
