The idea has been revealed in documents published by Leicester City Council seeking sponsorship for events to mark the Festival of Light. It describes the proposal as part of "innovations" planned for 2015 to around the religious occasion celebrated by Hindus, Sikhs and Jains.
The festival would run from the planned switch on of the Diwali lights on The Golden Mile on Sunday November 1, to Diwali Day itself on Wednesday November 11 and then on to November 15.
Both the illuminations switch on and the closing fireworks displays have been arranged by the city council since the 1980s and usually to attract between 30,000 and 40,000 visitors each.
A spokesman for the council's arts and museums service said the aim was to link the two showpiece events with other events arranged by community groups or temples.
The council is putting £88,000 into the 2015 Diwali celebration and is seeking private sponsorship as it has in previous years.
