Not a credible proposal. No such satellites have been launched---and, if you think they have been, kindly provide the satellite designations, launch dates, and orbital parameters, particularly inclination and altitude. And proof that such satellites could be close enough (how close?) for long enough (how long?) in any mutual passage over Maui. Generally, for LEO satellites, you have only minutes to pass from horizon to horizon.
Phased arrays exist, but only as monolithic systems (one emitter). Two things are essential about phased arrays: a rigid and constant-dimensioned framework for the array elements, and a common, high-precision timebase. We do not have the technology to control these elements for two, independent arrays. The net result of current methods is that all you will get will be "side lobes."
Metal reflects microwaves, so in order to melt aluminum, you would have to scorch the rest of the island at maybe 40 watts/cm2, or 0.4 megawatt/meter2. And this would be a much larger spot than a square meter, because small target spots would require a large satellite aperture. So, the requirements for power and aperture are prohibitive,.
The video of the melted wheels is sheer ignorance and proves nothing about DEWs or side lobes. Similar effects have been observed at the California "Camp Fire" wildfire and the recent wildfire in Tennessee (I have posted the photos elsewhere on this site). At some point, you have to realize that is is a commonplace occurrence at wildfires.
I spent decades working on laser DEWs, and spent time on the AWACS program studying how to mount phased-array antennas on the airframe for a communications link. The more off-axis you point the beam, the less the intensity of the beam becomes. There is also the interesting and non-trivial problem of pointing the beam. At present, such beams are the mainstay of radar systems, which are all about pointing and detecting. In order to have a microwave DEW, it would have to be also an imaging radar system---which is very hard to implement, since the beamwidth would have to be as small as the desired observable resolution of the image. Back to big aperture again, and extreme precision on the timing of the wavefront phasing. Frankly, there is no way to show that you would be able to hit a discrete target, unless you simply wanted to flood-illuminate the target. It would be easier to drop napalm bombs.
Oh, and why would a LIDAR be necessary, if you already had access to surveyed topographic maps? You are just throwing everything into the kitchen sink in hopes of making a souffle.
Those two cars were sitting in an empty dirt lot. What could have caused the wheels and exhaust manifold to melt? And ehats the melting point of automotive glass? The windshield melted in both vehicles
The gasoline in the automobile tanks catching fire and burning beneath the car, and also setting alight the rubber tires. The melting point of automotive glass is about the same as the melting point of the cast aluminum wheels, substantially below the flame temperature of gasoline and rubber.
Only certain kinds of glass melt at higher temperature (e.g., fused quartz), not auto glass. For one thing, the auto glass incorporates a transparent layer of plastic (anti-shatter) that would certainly melt. You should read a little more.
The burning temperatures of gasoline and rubber are in the high 2000s. More than enough to melt anything with a lower melting temperature. The videos also evidence the fact that all the upholstery was burned up, which also releases heat.
Look for wider examples. This same kind of thing was observed in the California "Camp Fire" wildfire and the Tennessee wildfires.

Everything I've read has the wheels burning at 1200-1500 and glass at 2500.
Those two cars were abandoned and sitting there for a long time according to a few different videos I've seen made by loxals
