Falling block help

I have a hopkins allen 932 In 32-20, I picked it up cheap and it doesn't need much work. After cleaning the bore you can see it's pitted badly. So now for the million dollar question. Do I install a liner and go back 32-20 or how big can I go with an 1880s action and a cartridge that has a better brass selection?

I'm a big fan of falling blocks but I know nothing about the H/A and I'd hate to go with a 22 ackly hornet and it blow up after all the work.
Leave caliber in what the action was designed for.....
 
I think 38 special would be more inline with the 32-20 as far as respective pressures.
My 1885 was built in 1892 and chambered for the .25RF. It was in rough shape cosmetically, but mechanically very sound. I wanted an original Lo-Wall to shoot. I was considering several different calibers, but after much research I became learned about the limitations on chamber pressure limits of firearms from this era. I chose a liner for the .38 Special which is perfectly safe where .357 Mag is above safe limits.
