Battletech without Jumpships

The real hook for BattleTech is the 'mechs. The politics are part of the human drama that plays out within the 'mech-based paradigm.

The middle-ages parallels aren't subtle, so it makes sense that HPGs are a cloistered technology overseen by a pseudo-Catholic Church organization. Fair.

But the jumpship/dropship dynamic--the solar sail recharging, the 30 light year jump distance, the unmapped planets that are generally ignored despite being strategically useful, the warships, the tension between military and shipping scales--seem to grind the settings gears a bit.

The clunky robots bit work with the clunky interstellar bit, but it's a conceptual speed bump that doesn't seem necessary.

If you were to redesign the BattleTech universe to have a simpler method for interstellar travel, what would that method and that universe look like?
