Discovery pumper

[DonH]

 I've been thinking about it for ever. I've have a Sheridan Silver Streak a long time 20 yrs. or more. always wish I had a second shot or two.
Well, I bought a used Discovery and was wondering if they could add a pump to it? Like when a company added a second tube for longer shoot count.
 Is anyone making a conversion kit like that?
Thanks, Don
