Krypton Rampage liner replacement?

So I finally got these boots this past season and rode them the whole season. The fit is great on my foot and everything but I just feel that the liner sucks and their isn't enough padding in the toe for me. When I have the boot on just standing up my toe grazes the top of the liner like it's suppose to, but when I hit hard on a landing my toe will bang and it just sucks for a few minutes from there, it never does any major damage to my toes. Also the liner doesn't seem like it's very warm at all. Everyone I talked to that has had these boots said their toes get really cold. What kind of liner replacement should I be looking at that will fit in these boots properly. I really like the new atomic liners, it would be great if they were to fit in the boot well, with the lace system in the liner it would give me an even tighter fit to my boot, and from what I heard the liner is super padded.
