Devon roof canvas - repair or replace?

[m1c]

mine is old and tatty. i dont mind givin it a good clean but the wooden framework is old and has snapped in places and the lining has come away from the wood here and there.
ive managed to bodge it with ducktape for now but it'll need to come off if its to be repaired. or would it be easier to replace? would i have to replace with the same canvas or could i fit one of them ninja ones instead?!

cheers
