A new shirt fans can wear in protest (1 Viewer)

If a shirt was created which had the same design as the new shirt, but with a SISU out logo on the front and the coventry crest on the right, would supporters buy it? Should be able to get them manufactured and sold for under £10. This way fans can support the team by wearing the colours but also still backing the Not One Penny More campaign

They wouldn't be able to copyright the design of the shirt. Even if there was I'm sure 5 points of difference could be incorporated into it, such as having the taller stripes starting on the right, maybe dark blue shirt and light blue stripes etc. the badge I don't think is copyrighted as that is the reason Hoover tried to create the new one in 2005.
In terms of having SISU Out I don't think it is an ejectable offence. Could have NOPM instead?
With regards to the cost, I'm sure there would be a manufacturer in the city, or shirt printing company that would maybe accept payment for 50 upfront and then going forward do it to order, within reason. I.e once 20 orders are taken reprint.
