I've always been interested in doing a 30/30 AI, just because. If I had 3 working 30/30 rifles, I guarantee I'd AI one of them; why not? Sometimes it's not about making the numbers make sense; if you want to do it for fun, go for it. As long as you're not messing up a collectible rifle, you'd probably never regret trying it, but always wonder if you didn't.
Honestly I've never had much interest in a 35/30 though, having put a lot of miles on the 35 Rem I would (and did) just go with that factory round instead, for both levers and pumps.
