If...
water + wind is ice
wind + earth is magnet
earth + water is mud (I believe mokuton is water + earth + yang release so no, earth and water just make mud)
...then a bloodline of water + wind + earth should be something along the lines of freezing mud.
Before you leave, hear me out. mud is very malleable and flexible. Like dirty water. when made into ice, it would be brown ice. And you can change it's state from the solid (brown ice) form to it's liquid (freezing mud dirty water look) one.
When a person is caught by the freezing mud (find a name for it), they'd freeze till death or till the user decides to cancel the freezing effect on them.
The strength of it's brown ice form is 3 to 4 times that of regular made chakra ice.
And you can do the same things with it that a hyoton (ice release) user can do with their ice
(e.g. creating a dome of mirrors and hiding in them, also moving from mirror to mirror and jumping mirrors too, teleporting through any mirrors created and left behind as in enter a brown ice mirror and leave through one (can be the same one you entered in or a different one left 10million km away from you)
Special ability: you can freeze a person's chakra, their control of it, chakra flow and even their chakra circulation and system.
When they're covered in freezing mud, it's freezing effect will seep into the body or the part that's covered by it. The freezing effect is faster if the freezing mud is in It's brown ice form because of the solid projectile formed by the user piercing the body directly. Also freezes the physical body so physical movements are slower. Body temperature is lower.
When the freezing mud freezes a person's chakra, it slows down chakra flow alot so they can't utilize it or call upon it as fast as they did before. This ruins their control over it, as they can't summon chakra fast enough to the frozen part. Chakra flow is restricted and slower. It screws with chakra circulation and the system by freezing tenketsu so if a tenketsu is fully frozen, you will not be able to send chakra through it.
The freezing is temporary though and depending on how much chakra used will determine how long the freezing will stay for.
