Buying the same stove will at least keep all my splits the same size.
I don't think you'd want as big of a stove now that it's been brought up. But the BK's are renowned for low output capabilities sooo? For me the 2nd stove/insert upstairs can push things over the top real fast if I'm not careful and smart about it, but these are two hot running stoves.
I'd be worried that you couldn't idle two of the big BK's without cooking yourself out at times and you'd be stuck with either just running the basement like you are now or being easily overheated.
I agree a smaller stove would make sense as bholler pointed out. It would be cool to have a king and a princess if you like that look. I like plain looking stoves myself too. A black box that gets hot.
