I think Krystal could get in to Smash 4 without any Star Fox characters getting cut because:
From Super Mario games:
-Mario
-Luigi
-Yoshi (First appearance was in Super Mario World, unless you count Yoshi as having it's own games.)
-Peach
-Bowser
-Wario (His first appearance was is Super Mario Land 2: 6 Golden Coins, unless you count him as having his own games.)
*6 (6, 5, or 4) characters from Mario so far*
From Star Fox games:
-Fox
-Falco
-Wolf
*3 characters from Star Fox so far*
_ _ _ _ _ _ _ _ _ _ _ _ _ _
Adding Krystal to the Star Fox group in Smash would only make 4 characters from Star Fox, which would add up to less (or the same amount) characters than there are from Super Mario.
I thought you might have considered them clones.

Oh, sorry.Oh, TheAceLucario, I did state that, for me, Lucario and Ike were the most likely to be cut, but that's not because I consider them clones.
