Some time ago I also had only a 600V Fluke DMM, and I needed to measure +Boost on a TV (near 900V). I carefully ajusted a attenuator asing the 600V range (on manual range) using lower voltage and a relatively robust potentiometer. then, I sub it with a array of series 1kV rated resistors to achieve correct value, and measured perfectly on the 600V range (in that time, I only made a 2:1 att; eg. 900V reads 450V).
Nowadays I restored a tube MM, using HV resistor on voltage scale divider. Resulted limited only by switch, and I comfortably use it's own full 2kV scale without any trouble.
Thanks for the explanation. My knowledge is patchy so I will wait until I can get a higher rated MM instead of improvising.
