You can also get fixed up at this site, but it looks like it would be kinda pricey.
http://eabco.com/ . They have a rimfire conversion kit that actually replaces your firing pin, but then you have to buy the barrel from them. If I'm not mistaking, the site KYODE posted sells barrels that are offset to use the factory firing pin. I would also like to to shoot rimfire in my encore, but may end up just getting a G2.
