Felt glued over the other felt on backrail

[steste]

Hi,
i have since few weeks a Rhodes MK1 '77 and i'm doing some maintenance in simply way, just experimenting and having fun.
I'm doing some improvemet on key bushing on some bad key and now i see that the backrail felt is hard, maybe due to time.
What you think if i glue another thin felt over the old felt without removing it?
This because i shloud so without removing the action rail just removing the name rail and the keys...
Its really a blasphemy or somebody have tried to glue a felt over nother?
The new felt that i have is thin,  1mm thick so i suppose that doing this i will adjust also the key dip that now is 10-11mm.
Thanks ciao from Italy

Disassembly of the whole action is done in 5min....

So if you want to improve your instrument, take your time. I'd not glue a felt over another. This would lead to inconsistent key dip.
