Would you consider 50 Gy in 20 fractions for a primary head and neck malignancy in an elderly patient with poor KPS?

For a non-metastatic head and neck cancer patient in his early 80s with an ECOG PS of 3 who has already lost about 20 pounds, how would you favor approaching treatment? Would you consider the Princess Margaret palliative regimen of 50 Gy in 20 fractions with a break midway (similar to the HYPNO trial)?
