Great Britain captain Anne Keothavong says the Fed Cup must not be "ignored" while so much "time and energy" is being devoted to Davis Cup reform.
GB will be promoted to the World Group for the first time since 1993 if they beat Japan in a play-off this weekend.
In February, the International Tennis Federation (ITF) announced plans for a new-look Davis Cup.
"I hope the ITF value the Fed Cup as much as the Davis Cup - and give women a chance to shine," said Keothavong.
Unlike the Davis Cup, the World Group of the women's event is currently split into two divisions of eight teams.
