It might be worth looking at a multiple-resistor arrangement as is often used at HF; it depends on how good you need the SWR to be.

Practical Wireless in February 1987 published a design for a 100W load that used resistors in parallel; its performance was quite good;



Some experimentation with small capacitance might improve it at the high end.

I believe that not all resistors are happy in some oils. I remember G5RV finding that out with cooking oil...worth being a bit careful.
