Legacy honeywell system has wires running back to a traditional panel for power. Original plan had been to use those wires to power the IQ Panel 4 and the IQ Panel Remote. Imagine my surprise when I discovered they are different voltages (seems like a serious engineering oversight). New thought is to provide 12v on the line as required by the IQ remote and use a buck converter to step down to 7v as required by the panel 4 at the panel 4 by adding a box behind it in wall.
Any thoughts on this or buck converters folks have had better success with than others (my experience with buck converters is mostly in the higher voltage ranges of 72v and 48v coming down to 12v and 5v).

No, be sure to never do this. Existing keypad wiring running between the old panel and keypad can be reused typically, but the wire must be disconnected from the old panel and connected to the provided plug in power supplies shipped with the IQ Panel and Remote. Do not use the old panel’s aux output.
Generally keypad wiring is 22AWG, so it is likely necessary to double up the conductors, use two for + and two for -
The IQ Panel 4 supports up to 98.5 feet on 18AWG. Doubled up 22AWG is effectively a bit thinner than that but if your keypad wire is less than 70 feet or so it should be fine.
Given that the panel 4 requires 7VDC and the remote requires 12VDC what is the best way to accomplish this? I’ve got a fluke and can get the exact length of the wires. Running new wire to the panels isn’t a practical option.

Can you clarify what you mean? The IQ Panel 4 and the IQ Remote each come with their own plug in power supply with appropriate specs for the device. They are powered independently.
You can reuse the existing wiring almost always, except in cases where the distance is very far. In a typical home this won’t be an issue. Double up the conductors to limit voltage drop.
