Conclusion-
Gaara cannot beat hebi sasuke
I find I funny that you're using kid Gaara as your example when Current Gaara has shown greater defensive feats and power. That's like me saying Sasuke's is slower than Jonin ninjas and showing you Kid Sasuke getting beat by Kakashi in the bell test. Kimmimaru's bones are as hard as steel which is even stronger with CM lvl 2, also Kimmimaru base was like jounin level so a chunin level vs a jounin level was the scans you used. You didn't even used where Gaara's shield broke Kimmimaru's strongest bone

which didn't flinch and was made almost instantly. Kirin destroyed a hollowed out mountain, its hollowed out because we saw Sasuke and Itachi inside it and if it was really a mountain buster then Sasuke would be dead, he was a few feet from Itachi. That means Kirin is a target attack that strikes it's target and Sasuke was just hit by the impact wave.If Karin does get thru

, it's power would be weakened and Gaara would still have his orb shield and the sand armor he wears so yes he has a chance of taking it and that was only Gaara's power, if Gaara used the 1 tails then he'll tank it no prob.
