"If it were me I'd convert it into fixed bias to lose the cathode bypass cap and I'd try to use some DHTs in the input and use an interstage."
Then you would very likely need a different output transformer to cope with the different operating point, as well as integrating a fixed bias supply, and potentially even a higher voltage coupling capacitor (if an interstage transformer isn't employed).
I don't think fixed bias is a huge advantage in class A unless you don't have enough power supply voltage.
