Maybe and Maybe! I had that conversion done last year on a .30-30 but they may have run out of the octagon barrels to convert your's. I don't know if the ejection port and other internals are the same as a .30-30 and I know the bolt isn't the same. My gut feeling is they won't because it would require the change-out of almost everything but the lever and the receiver. They will, however, do it on a .30-30. Call 800-544-8892 and ask them. The conversion is $280 including return shipping of the rifle and all you old parts.
North Woods, the bolt on the 35 rem is smaller than a 38-55 the 30-30 has the same case head to make that conversion a little easier. I would search the pawn shops, newspapers and gun show for a donor rifle in 30-30 then send it out to be rebored or rebarreled. The 30-30 can be done with a rebore for a little over a $100.
